Mobile applications have brought a revolution in the technology space. We have seen a massive paradigm shift as far as telecom technology, connectivity, and utility are concerned.

We have millions of mobile apps on different marketplaces, that can help you perform every possible task or activity you can think of.

Customers are also finding it more convenient to use mobile apps and that’s the reason why most enterprises are investing heavily in developing their applications to give their business a leading edge to remain relevant in this ever-competitive world.

However, building a successful mobile app is easier said than done, as it is a complex process, that demands a focused approach, efforts, and resources. An application’s success depends on various elements such as features, functionality, speed, usability, and many more.

While launching your mobile app, it is crucial to validate and ensure its Usability. Well, ‘mobile app usability’ might be a new term for you, do not fret as we will provide you with complete information about it and cover several aspects of mobile app usability.

In this blog, we will explain what mobile app usability is, its advantages, best practices, challenges, and a lot more.

 

What Is Mobile App Usability?

Mobile App Usability testing is a process of getting actual end-users to interact with your mobile app so that you can observe and assess their reactions, behavior, and interactions to it and make necessary changes to make it more user-friendly for them.

Mobile usability testing is an essential activity to ensure that you are developing an enjoyable and beneficial experience for your users.

Mobile App Usability

Usability testing plays an important role in the app development lifecycle, as it helps developers to validate the decisions, they have already made regarding app interface design, functionality, and navigation. It enables developers to prioritize new features and error fixes.

 

Mobile App Usability Testing – Methods

We use six methods to accomplish mobile application usability testing. Each one gives you deep insight into a wide array of questions about your intended userbase. You can select a suitable usability testing method based on your project goal and resource requirements.

Moderated and Unmoderated

Moderated tests are executed by a facilitator,  who conducts the test and addresses the user’s uncertainties and queries. Moderated testing enables a researcher to execute tests and ask follow-up questions for elaboration and clarification.

In this method, participants can perform tasks on their mobile devices while remaining engaged with the researcher telephonically via conferencing app like Skype, Teams, or Zoom.

Moderated testing yields results with in-depth insight. However, it may incur a high cost to organize these testing, as it requires a dedicated lab, experienced facilitator, and appropriate compensation for participants.

On the other hand, the Unmoderated testing is performed without a facilitator. Participants can design test tasks in a lab at their location. Unmoderated testing can offer quick results at a much lower cost, but it lacks accuracy in results.

It offers another drawback due to the lack of a facilitator, as there is no option to ask clarification or follow-up questions from the end-user.

Lab-based and Guerrilla Testing

Lab-based usability testing is one of the most used approaches to validate your mobile app design. Researchers can invite participants to a convenient location and implement a plethora of tools to gain in-depth insight.

Though some projects demand you to test the application design at the user’s location or environment, a user’s setting could be so specific, and it couldn’t be replicated in a lab.

Here it is important to note that usability testing at the user’s location or environment usually takes longer than other methods.

 

In-person and Remote

In-person usability testing provides researchers a larger context and deeper insight, that helps them to observe users’ facial expressions and body language. It is performed during moderated lab-based testing and could be performed remotely using a tool.

Remote testing

Remote testing may not offer you as deep insight as in-person testing, but it allows you seamless access to larger participants scattered over the different geographical locations at a negligible cost.

It also allows app owners to hire participants without thinking much about several constraints, for example, location and travel restrictions.

 

Card Sorting

It is an effective method to prioritize app features and content in the user interface. The researchers can place the content on virtual note cards, that can be manipulated by users into categories and groups. Once the cards are sorted out, the backed logic is explained to the users.

 

Eye Tracking

This usability method lets you monitor and evaluate users’ eye movements via advanced eye-tracking technology.

Researchers can observe the skimming trends to monitor the direction where the user is looking, the element they are interacting with, and for how long. Eye Tracking helps researchers to address usability challenges without intervening in the user’s natural flow.

Eye Tracking

Session recording

It is a method of recording the actions taken by the end-users in a real-time environment. It includes movements such as scrolling, clicking while using a mobile application.

Session recording provides vital data that enables app owners to observe the type of content that attracts better user engagement and understand the potential interaction problems user may encounter while using an app.

 

How Mobile app Usability Testing is performed?

Before discussing how mobile app usability testing is performed, we must understand how a usability test plan is developed, as it serves as a technical drawing for actual tests.

Mobile App Usability Best Practices

Well, you perform mobile app usability testing to identify bugs and errors in the code. However, you can follow some best practices to overcome common app issues.

Platform Compatibility

The most common issue that disenchants users from using an app is the lack of platform compatibility. While designing the mobile app, you must ensure that it performs well on all operating systems and platforms. 

iOS and Android are the most popular platforms, and both hold unique design, interface, and programming requirements. You must design a mobile app, that can function seamlessly on different platforms while providing a native-like experience. 

Offer Immediate Value to users

Users download and use those applications that offer them good value. You must ensure that users find your app valuable and helpful.

If your app failed to convince the user during the onboarding process or initial usage experience, then you may lose them forever. Offering appropriate value to the user results in lower abandonment rates and better performance metrics.

Easy App Navigation

App navigation is a critical success factor for any mobile application, as it can make or break the user experience. Your mobile app may offer a plethora of features and functionalities, but it is of no use if users struggle while navigating the app.

App navigation must be straightforward and it should prevent instances where users can get lost while using the app. Complicated app navigation may result in a higher abandonment rate.

Test mobile App In multiple environments

While conducting usability testing for mobile apps, it is important to test them in multiple environments and platforms. It helps you understand app behavior in different environments and take corrective action to make their function smoother.

Always dodge Testing on Prototype

It is always recommended to test your mobile app on the actual devices instead of using them on any prototype. This approach helps facilitators to better understand how the app functions on various devices and form factors.

Recruit recommended and correctly sized Test Group

Always select a group of people who have less experience of using smartphones. It is recommended to have diverse opinions from participant groups, as it helps you to develop a better app, that can address the concerns of a diverse userbase.

 

mobile app group testing

It is highly recommended to hire at least five users to perform usability testing for your mobile app.

Clear and Precise Content

While designing the app, always keep your app content straightforward and concise. Clear content helps the user to meet their objectives and improves their overall engagement with the app.

rtless Scrolling –

Always avoid copying your mobile app’s content and enhance it based on your application’s requirements.

Reduce the Steps required to complete an Action

You should ensure every action of your mobile app must be straightforward and precise to meet its intended goal with ease. It is necessary to declutter your app’s user interface, as every screen, image, button, or even icon can muddle the user flow.

It is recommended to use limited but essential UI elements and showcase important content to users to improve application usability and conversion rate.

Reduce Scrolling

You must provide necessary information to users within the screen limits only, which will help users to access most of the information without using the scrolling function.

It is always recommended to use side-scrolls sensibly, as sometimes it hides essential content.

Mobile App Usability Issues that can jeopardize your mobile app

Multiple issues can lead to unsuccessful mobile apps. It is important to consider these issues while developing and testing an application. Let’s Check Them Out:

Screen Resolution Compatibility

Screen resolution issues can jeopardize a user’s experience. Even if the Operating system is the same, the app may behave differently on different mobile devices, resolutions, and screen sizes. Mobile apps may look enthralling on one device and scatter on another.

Navigation Complexities

An application’s navigation enables users to catch up with the features and interact with the app modules effectively. If navigation is complex, then it may lead to user dissatisfaction and may lead them to exit the app.

Effortless Scrolling

Application scrolling is an extremely vital aspect of application design, as it offers an intuitive interface to the end-users. However, the side-scrolling must be carefully designed, as it may hide valuable content sometimes.

Infinite Typing and Tapping

A mobile app demands virtually unlimited typing and tapping by the end-user. However, it is always recommended to ensure all functions are completed with fewer steps, fields, pages, and buttons.

No Auto-Fill

Users may get annoyed if an application asks them to enter personal details frequently. To avoid such instances, the developers must incorporate an auto-fill data feature to make it more convenient.

This feature will reduce a lot of user load and help them to get instant search results.

User Feedback

It is extremely vital to fetch user feedback for developing a mobile application better. Usually, app developers let them go. The app should perform as per the users’ expectations.

Gesture Responsiveness

Lack of gesture responsiveness led to a bad customer experience. If an app user experiences issues such as mistaken elements, buttons not working, and substandard counter-intuitive gestures can jeopardize the app usability, and it may force a user to uninstall the app.

 

Conclusion 

Mobile application usability plays an important role in app success, and you must employ a well-structured approach to perform usability testing.

The best part is, that you can tweak this approach based on your business and app requirements, and an app could be tested to fetch reliable outcomes. 

Mobile app usability testing designates developers to pay utmost attention to the aspects that can make or break your application’s prospects. It also helps developers to validate the desired within a specific environment.

Developers can use app usability testing in various ways and stages during their project lifecycle. Though it is unable to mimic real-life usage, it is still the proven method to ensure your mobile app can meet its user experience goals easily and quickly.

If a business meets the expectation of their users, they are more likely to create a successful service and experience.
