Detailed Guide to App UI Design for Mobile App Developers

Chapter 1

Mobile Application

Let's get started by understanding the basics of the mobile application.  In this chapter, we will cover the basics of the mobile application.   

This chapter will provide answers to questions like "What is a mobile application?" and you will get to know Why is the mobile app important for business?.   

You will get to know, "How does a mobile application work?" and "What are the advantages and disadvantages of mobile apps?"  

If you are a business owner and want to know "How apps benefit businesses?" and "What are the types of mobile applications?" then this chapter is for you.  

In the end, we will also discuss, "What is a mobile enterprise application platform?"  

Mobile applications are the future of how businesses will work. Today most of the big players in the market are having mobile apps either on Play Store or on their website.  

What is a mobile application?

A mobile application is a portable version of applications or software accessed on laptops or PCs with the help of internet connectivity. These mobile applications provide you with similar functions that you access on PCs. 

Mobile Application Definition (Technical): A mobile application or mobile app is the term used to describe a software application that works on a mobile device. 


Mobile applications take full advantage of the hardware and software of mobile devices. For instance, a gaming application can take advantage of the iPhone's accelerometer. 

Mobile applications are developed to help users perform the activities that they perform on desktops or laptops.  

Generally, mobile apps are categorized into three categories:  

  • A native app is developed for any specific operating system like iOS or Android.  
  • Web App is the responsive version of websites that run on multi-platform (iOS & Android both).
  • Hybrid App is developed by combining the aspects of both native applications and web applications. 

Did you know that there are more than 2.2 million applications on the App Store, and 2.6 million applications are placed on the Play Store?  

In the year 2020, mobile apps (iOS and Android) revenue is expected around $581 billion.


Today, there are more than 3.8 billion smartphone users in the whole world, and each of them is using applications installed on their devices. 

After having a look at these statistics, you can quickly figure out how mobile applications are beneficial for business. Now let's discuss how mobile apps work.  

How does a mobile application work?

Technically, a mobile application is a software that is designed to perform any particular task on mobile, either online or offline. But do you know how mobile apps work?  

Mobile devices have limited hardware resources; thus, multiple tasks are avoided by an application.  

To make it simple, mobile applications enable users to choose the particular activity that they can accomplish with their devices.  

A basic mobile application is based on a software architecture that runs on a PC or laptop and gets carefully migrated to work on smartphones. But this technique will not be useful when the mobile application is more sophisticated or complex.  

The working of a mobile application depends on its type and functions. For example, there are three types of mobile apps where the working process of one app is entirely different from web apps and hybrid apps.

The above image is the technical working of a mobile application. To understand the functional operation of a mobile app in detail, you can check this article of Codeproject.   

After having an in-depth overview of the working of a basic mobile application, it's time to move forward to understand how different types of applications work and interact with the users.  

Types of mobile applications and how they work.

Native App  

A native app is specially designed for particular operating systems or platforms like iOS or Android. It is the reason that a native app can take full advantage of the device hardware and software.  

These applications work with the operating system of mobile devices that enables the applications to perform more flexibly and quickly than alternative application types.

Native mobile applications synchronize the information directly from mobile devices to apps and vice-versa. It is the reason native applications are fast.   

If the application needs to be published to users of different device types and OS, the developers create a separate native app version to accomplish the needs in a fast and effective manner.  

Some of the examples of native applications are Mail, Contact, Store, Photos, Music, and many more. These apps are preinstalled on Android or iOS devices since a native application is designed to work with the device OS.    

Native iOS and Android applications are mostly built on Swift and Java. These days, developers also use Xamarin to develop cross-platform native apps.  

Web App 

Web Application is the responsive version of a website that seamlessly runs on multi-platform (iOS & Android both).   

These applications work by syncing the information from the webserver and database. This information or data is transferred with the help of the internet through the browser interface.


The working speed of a web app depends upon the speed of the internet because, in web applications, the information is synchronized from mobile devices to servers and vice-versa.  

An organization can make a web application for any purpose. Generally, this includes online calculators, webmail, online stores, and more.    

You don't need to download the web applications as these are easily accessed through a  

network. Web browsers like Mozilla, Chrome, Safari, etc. play a significant role in easy access to these types of applications.   

The best thing is, you can develop a web application with a small team of developers since web applications have a short development cycle.   

Another reason for the fast development of web applications is that these are built using HTML5, JavaScript CSS and other programming languages as per requirement.   

Hybrid App

Hybrid App is made with the qualities of both native application and web application.  

A hybrid app is a web application that is embedded in a native shell application.   

The hybrid application works the same way as the web application. The only difference is, it can easily be accessed and downloaded natively on different platforms.  

The hybrid app is made using Javascript, CSS, and HTML5, where the entire code runs inside the container.    

Why is the mobile app important for business?

According to the latest survey in the United States, 97% of the population uses smartphones. It means nine in ten people are using smartphones.

"Did you know, in the last 6 months 79% of the users have used their smartphones to make online purchase."

After realizing the importance of mobile business, most of the large and small-medium companies have built their mobile applications. 

Companies that have developed apps for their businesses are at leading positions in their sectors and taking their marketing strategy to the next level.   

There are a lot of benefits to mobile applications for your business. We will discuss five significant benefits that will provide a better overview.  

But before starting with the discussion, let get started with this infographics:   


Now we will discuss all the 5 five benefits of mobile application development.

Better Visibility

On average, a smartphone owner spends at least 162 minutes on his mobile every day. This also includes the time he/she spent on scrolling through the application.

1. Native App

Native app is a platform-specific app which is designed on platform-specific software. An android app is built on the Java platform, and an iOS app is built on Swift or Objective C.

With this infographic, you will understand the advantages and disadvantages of Native Application:


However, native applications are quick, smooth, have complete access to the device, and can work without the internet, but still, these become challenging to develop.

These challenges include the time-consuming development process and higher development costs. These make it hard for those businesses that have less spending plans and additional time. 

2. Web Applications

A web app is designed for mobile devices. It uses web technologies and web browsers to perform the task.

Web Applications are built on HTML5 and Javascript.

Advantages and Disadvantages of Web Apps 


A web application may not be able to perform tasks for every organization.

3. Hybrid Apps

The hybrid app is made up of the properties of both native applications and web applications. A hybrid app is a web application embedded in a native shell application.

The hybrid application works similar to a web application and effectively runs as a native application. These are available in downloadable formats. The hybrid app is built on JavaScript, CSS or HTML5. In a hybrid application, the code runs inside the container.

Here are the advantages and disadvantages of Hybrid Apps:

Considering the advantages and disadvantages of web applications, we can conclude that web applications are a preferable choice for small and medium businesses with low cost and less development time.

What is the mobile app development process?

There are more than 200 billion mobile apps on the app stores developed for different platforms.   

Just like SDLC (Software Development Life Cycle) in software development for PCs, there's MADC (Mobile App Development Cycle) in mobile application development to develop highly-interactive mobile apps.


Creating an excellent mobile app is a process associated with extensive pre-planning. The mobile app development process involves a strategy, design, and development process. With that said, here's a look at the app development lifecycle, objectives and the challenges encountered along the way. 


1. Idea 

To build a great app, you need to have a good idea first. Without a good idea, you can't continue with app development.   

You have to ask yourself questions by keeping the app idea in mind that entails what the users' problem is and how you can solve it.   

You need to do an analysis of the problem and need to figure out why no one else has built the app for that problem. Speaking with other people about the app idea can help you get the appropriate results. 


2. Strategy  


After having a perfect idea, you need to figure out who your competitors are and what they are currently doing to attract users and make a strong customer base.   

You will have to find out the number of similar apps installed, you need to check its reviews and ratings, and you also need to check the app and background history.   

There are two main objectives of this process:  

  1. Learn as much as you can so that there is a minimal amount of mistakes.  
  2. Find out how fierce the competition is in the market and how many users are eagerly looking for such apps. Try finding out the niche of your competitor and convert it into a benefit for your app.  


App monetization is an essential step in your app development strategy. If you want your app to make money, then you will have to make an app from your user's point of view.  

There are various methods of monetization like subscriptions, in-app purchases, ad-revenue, premium features, paid apps, and by selling user's data.   

You need to do proper market research to find out the latest trends if you want to monetize your app.  


App marketing is all about finding the challenges in the market while launching your app. It's like planning for the 4ps that include product, price, place, and promotion before starting a product of any product or service. Remember that there are a lot of applications on play stores that are beautifully designed and crafted but are unused.   

So, first, you will have to find out the potential usage of your application. You need to figure out solutions to questions like: How many people are downloading apps similar to yours? Will your application be able to solve their problems?  

You need to understand your approach and the overall budget. 

Road Map 

It is the last stage of app development strategy. Preparing a roadmap of your app includes understanding of your app future and steps needed to make it successful from day one.   

Here, you need to prepare a list of all the tasks that your app will perform and rank them according to the priority. As you gain users, you will get to know what functionalities need to be added.    


3. UX Design  


In this process, you will decide what functionalities and information you need to keep in your application and how they will be organized.  

You need to prepare a list of all the tasks that your app will perform and rank them according to the priority and what is required to be displayed in the app.   

You will need a whiteboard, pencil and paper.  


In this stage, you document and wireframe the application to analyze the future trends.  

Wireframing is significantly something beyond just creating an app architecture; in reality, it's a pillar of your application.   

Wireframing helps you understand the flow of the system and gives you an idea of how it will work. Further, this enables you to estimate the project development timeline.   

Requirements: AdobeXD/Sketch, whiteboard, marker, Balsamiq, and paper.   

Learn more about Role Of Wireframes In Mobile App Development 


Workflow is the path in which your mobile app users travel. Understanding your user's activities and monitoring how many clicks are needed to perform that task.  

When you find any problem within the workflow, you need to wireframe that section again and retry.  

Requirements: You need invisionapp, whiteboard and marker, and paper.


NMG has created a video on invision. You can add it here to make readers the workflow of the tool.  


4. Development  

After putting a considerable effort in the application design and structure, you now realize your vision.   

In this step, you will define the tasks to the developers to achieve the defined objective of a  mobile app   

The best part is you can see the progress of your mobile app with the help of  project management tools such as Trello and Basecamp where every activity is being recorded and tracked appropriately  

Technologies for Android Development  
Languages: Kotlin, Java 
Database: Realm, SQLite 
Tools: Android NDK, Android SDK 
IDE: Android Studio  

Technologies for iOS Development  
Languages: Objective C, Swift 
Databases: CoreData, Realm, SQLite 

5. Q/A testing   

Q/A testing is generally carried out by non-developers or any developer in the app development team. It guarantees a genuine and quality app testing experience. There are several types of tests that need to be emphasized during each sprint. The test types are   

Functional Testing  

Functional testing is done to test the app against the functional specification/requirement of the client.   

App test engineers use the information that was gathered at the initial stage of requirements analysis to test an app as their test cases. It helps them to check whether or not the project is going as expected. 

Performance Testing  

No one is going to use your application if it is taking 15-20 seconds to display a list. This is the reason app performance testing is essential.   

The purpose of performance testing is to test the system for stability and scalability under various load conditions.   

It also detects potential web constraints to examine the structure and operation of a website under high stress. The primary aim of this testing is to ensure that the system is performing well and behave well when utilized by the users.   

Usability Testing  

Usability Testing ensures that the features of an application are intuitive and user friendly.   

In usability testing, HCI (human-computer interaction) factors of a system are measured, and flaws are identified for further improvement.  

At this stage,  the development team monitors the screen of the user to know how the selected user is interacting with the website. 

What languages are used for mobile app development?

In the last five years, the mobile application development industry has multiplied in leaps and bounds, changing the way businesses operate around the world. There's one thing sure behind their success, the idea and implementation of the mobile app.    

Therefore, if you want to understand your mobile application idea, plan it, understand the target market, and also decide the platform on which you preferably want to develop your mobile application.  


Language and development platform selection is the most crucial part, as the whole process is based on it. So, always make sure to choose the best and suitable one to carry out the proposed mobile development. Here we're mentioning the six best and most demanding languages for mobile app development:  


Hypertext Markup Language (HTML) is a well-known language for presenting and structuring the content on the internet/WWW (World Wide Web).   

It is the 5th version of HTML, which we called HTML5, where the text and tags are more familiar than the previous one. HTML 5 is more compatible with all types of scripting languages.  

There is a CANVAS element in HTML5 that is used for a lot of things in embedded applications such as online/offline games, dynamic graphics, interactive audio and video, and animations.

When it comes to developing Android Mobile Apps, Java language is one of the most preferred among all.   

It is Class-based, Concurrent, Object-oriented and, explicitly designed to have a few implementation dependencies.  

This language has a set of large, well-written, and standard class libraries.  

Objective C 

iOS developers choose Objective C as a primary language for the development of iOS applications. Apple chose this language to build scalable and robust applications.

Mobile App Design

Here we will discuss "What is a mobile interface? and "What are the best mobile app design tools?"   

 Going through the chapter, you will understand, "What is a mobile app wireframe?" and "Why is wireframing of mobile apps important?"  

After understanding the wireframe, we will discuss "What is app prototyping?" and "What's the benefits of app prototyping?"  

These are the aspects that we're going to cover in this section. 

What is the mobile interface?

A mobile user interface (UI) is a touch-sensitive and graphical display on smartphones and tablets.   

In simple words, it's a software that allows users to communicate with the functions, features, and other controls of the device applications.  

Mobile UI is not the same as you find on desktops. The difference between both can be explained by considering the operating system as an interface among users and hardware. The OS may enable the device to be utilized independently of any User Interface.   

A designer's responsibility is to create the UI that meets user requirements and make the experience satisfying and pleasing for the users.   

To make an attractive user interface, designers need to jump further into the particulars of mobile applications.  

User interface design is an essential part of an application. A perfect mobile user interface design should have useful functions and should be easy to use.  

Know about testing UI, Android UI, best practices, and much more on mobile user interface here 

What is a mobile app design?

When an app is built, developers look at the functionality process, whereas designers focus on making the app good in looks and feel.  

Mobile application designing involves planning than determining what fonts and colors are used for the interface. Deciding the further designing aspects, you must keep your users and their objective of use in mind.   

Designing a mobile application incorporates both user experience (UX) and user interface (UI).   

Depending on your target audience and purpose of design, you can choose the platform for mobile app design.   

Some of the popular options for app designing includes Adobe XD, Adobe Photoshop, and Sketch. Both Sketch and Adobe XD are built-in with prototyping and designing.    

Adobe XD and Sketch streamline your work processes and are focused on building a robust user interface and user experience.

Mobile application design is not an easy task and can be very complicated sometimes.   

Here, we have created a list of do's and don'ts of mobile app design that will simplify the process of designing a mobile app interface for you.  


  1. Proper Research: Do adequate research before you start working on your app. This will help you figure out your target audience and their needs. You can do this through competitive analysis and user identification.  
  2. Limited Features: Try to design apps with limited features by prioritizing mobile application requisites.   
  3. Remove Clutter: Wipeout clutter from the UI as it can overload the user with unwanted information.  
  4. Better navigation patterns: Use navigation patterns that your target audience is familiar with. Design a simple architecture so that it will require a minimum number of actions.  
  5. Smooth Navigation: Guide your users with a clear path.  
  6. Clickable CTAs: Provide your users with finger-friendly buttons.  
  7. Fantastic Content: Text is a mandatory requirement for every mobile interface. Attract your users with incredible content.  


  1. Don't try to create a design that's perfect for your first attempt. You should go with an iterative design approach and test to make it scalable to provide users with an excellent user interface. 
  2. Don't try to design in segregation. 
  3. Try not to ask for permission at the beginning.  
  4. Don't use acronyms, cultural-specific axioms, brand-specific terms, and technical terminology.  

You need to work hard today to win the people's expectations. These do's and don't will help you reach and meet the customer's expectations.  

Wireframes and App Flow

A wireframe, also known as screen blueprint or page schematic, is a visual guide that represents the skeletal structure of a website.   

Wireframes are made to arrange the elements to serve a particular purpose. 

What is a mobile app, wireframe? 

In a mobile app, a wireframe is a future vision of how an application will work. It describes how users will use and navigate through your app.   

What wireframes portray?   

  • Page element 
  • Content priority 
  • Commodity categories 
  • Visual branding element 
  • Possible actions  

The wireframe itself serves as the destination so it can support the developers with better strategies to accomplish mobile app development.  

You can use Sketch and Adobe XD for creating your app wireframes if you are looking for something collaborative and hi-tech. There are two more tools for wireframing, Omnigraffle and Balsamiq 

Why is the wireframing of mobile apps important? 

A well structured wireframing provides you a clear perception of functionality and design of the mobile application.  

It provides a fantastic start to build up your application in addition to the decisive set of features that will give you success and benefit.   

Here are the benefits of wireframing:   

  • Wireframe makes communication crystal clear, and this is the reason that makes it popular among the developers.  
  • From the beginning of the project, a wireframe keeps the team and developers focused instead of going behind the first idea. They can always refer to the wireframe; it helps them as a guide. 
  • You can make a unique strategy with the blueprints provided by Wireframing. 
  • Wireframes are your goal, but in the 2D format, your journey is accelerated when your goal is in sight. 
  • It helps a lot in speeding up development. Good speed is a gift for mobile development projects.  

All these benefits are enough to prove that wireframe is very crucial in mobile application development.  If you want to know about wireframing in detail, then we have an article written specially on this topic, "Role Of Wireframes In Mobile App Development." 

What is the app flow? 

The user experience of your mobile application is everything. But it is not sufficient to concentrate on the presentation of the pages in your app.    

You need to keep in mind how your pages in the mobile application are linked to others, where will call to action redirect, and the most important thing, how users will complete their task.   

App flow is the defined path for a user, which he will follow throughout the mobile application to complete his activity.   

It will take the user from the entry point, following the steps, to reach the destination/ final action that includes subscription or purchasing or any other outcome.   

Top five steps of the app user flow:   

  • You need to understand the user flow by user testing  
  • Defining users and clear business objectives   
  • Visualize your user flow by Wireframing 
  • Using scenarios for defining efficient user flows 
  • Do user test again  

Learn more about app user flow in detail here. 

How does the flow of an app work? 

Before designing the layout of an application, a developer needs to work on the structure and flow. Wireframe plays an important role here.   

Wireframing helps in understanding the user's behavior and how they will navigate through the application. 

Mobile App Mockup

What is an app mockup?  

In the field of design and manufacturing, a mockup is a scale or full-size model of a device or design, which is used for demonstration, promotion, teaching, and other purposes.   

A mockup is a prototype if it provides at least part of the functionality of a system and enables testing of a design.  

Simply, the mockup is a visual representation of a product.   

Since a wireframe mostly represents the product's structure, on the other side, a mockup displays how the product is looking.   

But still, unlike a wireframe, mockup is not clickable; instead, it is either a mid or high-fidelity display of the design. 


What are the different ways to create an app mockup? 

Mockups can be made with the help of various mockup tools that are available in the market. Here is the brief of the all the tools:

App Prototyping

What is app prototyping? 

App prototyping is a type of user analysis or research for validating the strategic design direction of a product. A prototype is the first view of a working product.  

Prototypes provide the look and feel of the product that helps analyze how customers react and use the overall UX design. This is the reason; prototype testing is essential for user-centric app development and design.   

Prototype (preliminary and iterative) research is conducted to make sure that mobile application design is enjoyable and easy to use, also aligning all decisions of strategic plan to user needs and to secure the project's ROI.   

What are the benefits of app prototyping? 

There are a lot of benefits of app prototyping. Mobile application prototyping keeps the client in front of the design process and includes stakeholders while looking for new thoughts for development. 



Here are the four significant benefits of app prototyping:   

1. Discovering new ideas and identifying product improvements  

App prototyping validates an initial concept and provides a chance to find new ideas/thoughts in the development procedure.   

In the design thinking process during the prototyping period, user testing can help recognize potential improvements before finishing the product.   

A prototype is the foundation of the product that ceaselessly improves till the mobile application is marketable and meets its business objectives.  

2. Cost-efficiency 

You might have heard that it's easy and cheap to resolve any problem at the beginning of the development rather than in the end after the problem occurs. Corrections at the end can cost very high.   

That is why app prototyping is essential at the beginning of the app development process. This saves costs as well as minimizes the possibilities of errors.   

3. Customer and stakeholder involvement 

During the prototyping stage, it is helpful to include the most significant stakeholders in the process of planning.  

As much as possible, partners should co-own the project's ideas, design, and decisions.   

A Collective approach of prototyping assists with ensuring that the final product intently reflects the organization's features and ideas, while ultimately meeting specific project objectives. 

4. UX Verification 

Feedback for application design isn't limited to what it looks like or feels (UI). The thing that matters the most is the interaction with the application (UX).   

By revealing the application prototype for testing, you can hear what clients feel about application usability. 

What is the difference between wireframes and mockups?

Wireframe and Mockups both help in taking strategic steps and decisions before developing the app.  

100+ checklist to develop a world class mobile app.


Both have different features and benefits that we will discuss by differentiating them.  



What is the difference between a mockup and a prototype?

You save a lot of money by building your design from mockup and prototype.  

It is easier to change the structure and logic at the mockup stage than the prototyping stage. Here are the differences between Mockup and Prototype.

Android App Development Language

Mobile applications have become a vital part of our day by day lives. We use them to connect and obtain valuable information.   

Developing a mobile app requires guidance, particularly in choosing the correct programming language. So let's start by discussing Android app development languages.  

What is the language used to develop Android apps? 

While various languages can be used for Android app development, Java is the official language that is widely used by the global app developers.  

Top 4 languages for Android Application Development  

1. Java 

Java has a massive community of developers that support developers when they face any problems.   

Java is a complicated language and needs expertise in complex topics like null pointer exceptions, constructors, checked exceptions, concurrency, etc.   

Overall, Java is one of the best languages to enjoy Android application development.   

But if you are not familiar with the complexities of Java, then there are more languages on which you can build your applications.   

2. Kotlin  

Kotlin is a cross-platform mobile application development language that is used as an alternative to Java.   

Kotlin runs on JVM (Java Virtual Machine).   

One of the significant differences you will find in Kotlin is that it removes Java's sophisticated features such as null pointer exceptions.   

Also, there is no need to include semicolons at the end of every line.   

Overall, Kotlin is very simple to use in comparison with Java, especially for beginners, and can also be utilized as an "entry point" for Android app development.  

3. C++ 

Developers use C++ with the Android Native Development Kit for developing Android applications.   

You can not wholly develop an Android app only with C+. Native Development Kit helps in utilizing the libraries of C++ code for the application as per requirement.   

This is done by implementing part of the application in the native code of C++.  

On the other hand, C++ is not very feeble, and also, it's challenging to set up. Also,  it's complexity can result in more bugs. 

4. C# 

C# is very much the same as Java, and that's the reason it is used to develop Android applications.    

Similar to Java, C # to implements garbage collection to lower the chances of memory leaks.   

Coding in C# is much cleaner with simple syntax in comparison with Java, and this is the reason C# is easy for coding.   

There are various types of applications like Music player, Chat Messenger, Game, etc. that can be built using the above mentioned four languages.   

There are few more languages like Python, HTML, CSS, JavaScript, and Corona that can also be used as ideal platforms to develop Android app development.   

Which is the best software for android app development?


Xamarin is a cross-platform framework owned by Microsoft and often referred to as an intelligent framework for mobile app development.   

This framework is combined with various features that are useful for creating quality Android, Windows, and iOS apps.  

Android Studio  

Android Studio is the official IDE (Integrated Development Environment) for developing Android applications.   

Android Studio features include APK analyzer, flexible build system, visual layout editor, intelligent code editor, firebase for implementation, real-time profilers, TODO functionality, Device File Explorer or Device Manager, Version Controller, Resource Manager and many more.   

It also supports Android X, which is the latest platform for Android development.  


PhoneGap is a product for app development owned by Adobe. PhoneGap is known as one of the fastest app development platforms  

PhoneGap also allows developers to reuse code, once written, to create hybrid applications.  

With the PhoneGap, developers can utilize the power of the Cordova plugin while using different frameworks for the development of Android applications.  

The best part is that the Cordova plugin enables the framework to interface with native APIs, for example, accelerometers, GPS, cameras, messages, and calls that result in native application experience.

You want to expand your business, and for that, keeping a close analysis of regular and new users coming to your app is mandatory.  

Mobile app testing is the best practice to get accurate reports on gross app traffic and users' behavior.   

This technique is one of the best to check the user’s interest in an app.  

Here are the top 3 benefits of mobile app testing:  


1. Optimize In-App Experiences  

When it comes to analyzing the performance of an app, in-app engagement is considered as the deciding factor. You can improve it by generating ideas for mobile app testing.  

The test will ensure that you continuously have the solutions to make your in-app experience more comfortable.  

2. Mobile app testing ensures increased conversion rate  

With the help of mobile application testing, you can attract users and convert them into buyers.   

In A/B  testing, you run different levels of tests in which two different mobile app versions are compared for quality and performance parameters.  

3. Mobile app testing helps in reducing the bouncing rate of apps 

It feels awful when your users jump to other pages without looking at your app or spending time with it.   

Mobile app testing reduces this risk of bounce rate because it helps businesses or developers to analyze, discover, and fix the issues to provide the best user experience.   

To deeply understand the concept, you need to know how mobile app testing works.  

How Does Mobile App Testing Works?

Mobile testing is done in several stages that are given below:   

1. Documentation Testing 

  • In documentation testing, a developer needs to inspect the requirements for completeness and discrepancy.  
  • Whatever the discrepancies are found at the documentation testing stage must be resolved before development begins.

2. Performance Testing

What are the significant mobile app testing challenges?

Most of the organizations either don't have time, or they don't have the proper tools for testing mobile applications.   

There are various real-time challenges to conduct mobile app testing. Here, we are going to discuss three significant real-time challenges of app testing.   

Top 3 Real-Time Mobile App Testing Challenges   

1. Non-linearity of mobile UX because of high test complexity  

Unlike mobile sites, conversion funnels, application flow, and user experience in mobile applications are not linear. 

2. Involvement of developers for end-to-end  implementation 

Mobile app testing enables you to test on the server-side to optimize your whole stack. This enhanced scope requires SDK download and needs a developer to run the test successfully.  

3. Delay in publishing app in the market 

A/B testing of mobile applications includes several processes that delay the time of making apps live in the market.   

For each application update, App Store approval is required, and for this, you need to wait, and after the approval, users can update the app.   

This was all in the mobile application testing section. We have covered all the major topics. Let’s now move forward to Mobile App Developer.
