According to Toptal – 90% of users stopped using an app due to poor performance. Therefore, developing an intuitive mobile UX that drives customer engagement and reduces churn is crucial.

However, before heading towards mobile application development and management, it’s essential to consider Mobile App Usability to build successful and functional mobile apps. Here the term ‘ Usability’ is a quality attribute (QA) that analyzes how simple it is to use a user interface. It enhances the performance, reliability, and satisfaction with which specific users achieve their objectives.

A successful app should be intuitive and take users very little time to become familiar with the interface. When a user gets stuck, a solution should be readily available. Using mobile app onboarding, you can guide users through a mobile app, improve its usability, and fix errors.

But how do you improve the usability of your mobile app?

Mobile App Usability Testing is the best way to build successful and functional apps and ensure the ultimate mobile experience. It allows you to gain deeper valuable insights before developing your app and determine which enhancements are necessary to implement in your app’s design.

In this article, we will explore what is Mobile App Usability Testing, its importance, its benefits, types of Mobile App Usability Testing, and how to perform it.

Let’s begin!

What is Mobile App Usability Testing?

Mobile App Usability Testing is a type of non-functional testing that evaluates an app for user-friendliness, modern web design, and whether it’s meeting the end-user requirements as expected.

It focuses primarily on mobile UX, testing design glitches, improving usability, and providing users with mind-blowing user experiences on different browsers and operating systems. Check our blog to learn how cross browser testing ensures a better UX.

The application’s success relies on the end-user. So the ideal approach to conducting Mobile App Usability Testing is with actual users representing the target audience interacting with your app. You can then observe their interactions and behavior, collect qualitative and quantitative data based on your observations, determine user satisfaction and critical usability issues, and make UI tweaks accordingly. You can also involve highly-skilled software testers to run user test cases that simulate actual user interaction and behavior.

Why is Mobile App Usability Testing important?

Users are five times more likely to abandon a task if a website is not optimized for mobile – Toptal

The primary objective of Mobile App Usability Testing is to deliver user satisfaction, lower time on customer support, and boost business sales and revenue. For example, there may be instances where your product or application works fine from the functionality perspective but lacks user-friendliness. Therefore, it will eventually impact your business revenue.

Usability Testing

Conducting Usability Testing of mobile applications helps reduce anomalies and improve user experience. Below are the main reasons why to perform Usability Testing of mobile apps.

  • Discovering Problems: One of the most important aspects of Usability Testing is user preferences and satisfaction. Running Mobile App Usability tests with various real users allows you to gather feedback and identify user-experience challenges. This feedback will equip you to mirror your product to user preferences.
  • Identifying Opportunities: Performing Mobile App Usability Testing of apps helps minimize design inconsistencies and enhance UI design per user requirements.
  • Explore User Preferences: Learn about user-specific preferences and behavior and the devices and screen sizes you currently support.

Benefits of Mobile App Usability Testing

Usability Testing of mobile apps help you identify product glitches and fix them before shipping to the market. Actual user feedback helps improve your product based on the real user requirements.

Testing the usability of mobile apps has many benefits. Let’s take a look at some of them.

  • Cost reduction: Incorporating Usability Testing earlier can reduce the costs.
  • It is 100 times cheaper to fix issues than to write a single line of code. – Jakob Nielson

  • Identifies unnoticed bugs: There can be a scenario where developers may overlook some bugs. Conducting Mobile Usability Testing for apps helps identify the unnoticed bugs, estimates the time required to complete a specific task, and reports if it differs from the anticipated time.
  • Actual user feedback: Mobile App Usability Testing with actual users helps in getting honest feedback from the users rather than relying on a false assumption.
  • Fresh insights: A user without knowledge and experience of your app can provide honest feedback and uncover unaware issues.
  • Evaluate user satisfaction: It helps evaluate user satisfaction, i.e., how happy your users are with your app.
  • Identify user needs: By running usability tests, you can discover the user’s needs, such as the features or services they desire, as well as several other aspects that your application does not support yet. It also helps increase your retention rate.
  • Minimize onboarding bottlenecks: It helps optimize your onboarding process by identifying potential customer issues and reducing the overall churn rate.

Different types of Mobile App Usability Testing

Before selecting the different Mobile App Usability Testing types, you need to specify your target audience, their behavior, and interests. After that, you need to set your objectives, the task you wish to perform, and their expected outcomes. Based on this, you can choose the appropriate type of testing that matches your requirements.

Check out some of the different methods of Usability Testing for mobile apps –

Moderated testing

Moderated Usability Testing is carried out in a lab setting. It involves a moderator who guides and helps test participants if they have questions about user interactions and behavior. One can perform Moderated testing both in-person or remote. Moderated testing provides in-depth feedback and qualitative data but is time-consuming and expensive. Also, this type of testing consumes a lot of resources, so it is generally used by large organizations.

Unmoderated testing

Unmoderated Usability Testing can be carried out in the lab or remotely without supervision. This type of testing doesn’t involve any moderator; therefore, test participants don’t have the opportunity to ask questions. Unmoderated testing is generally less costly, saves time, and helps you gain a lot of quantitative data on your app’s performance in real-user scenarios.

Lab Usability Testing

Lab Usability Testing involves a moderator and is carried out in a Usability Testing environment. The moderator asks questions, gives instructions, and responds to feedback while participants complete tasks on their devices. Although Lab Usability Testing provides comprehensive information, it is typically time-consuming since it is limited to a small group of people.

Guerilla Usability Testing

Guerilla Usability Testing is a type of Usability Testing technique in which random people are selected from the mall, airport, or coffee shop to perform a usability test in exchange for a small gift or coupons. This type of testing lets you generate a huge amount of qualitative data to understand the design and functionality-related changes of the product. However, Guerilla Usability Testing doesn’t get you extensive information about the product or application as people usually spend less time running ad-hoc tests .

Contextual inquiry

Contextual inquiry involves asking participants their feedback about using the app in their natural environments like home or workplace. It helps you gain relevant information about users like working preferences, interactions, and behaviors. This testing is needed when you are in the initial stage of product development.

Key steps for successful Mobile App Usability Testing

Here are a few key steps to implement Usability Testing for mobile apps effectively.

  • Setting Test objective: The first and most important thing is to set your test objectives like app roadmap, target audience, competitors, etc., and choose metrics to measure them. You can ask various questions to app stakeholders to explore the app’s various aspects. It will help you formulate your test objectives, select practical approaches, and estimate the budget early in the development process, making the entire process seamless.
  • Task planning: After setting the test objectives, you need to plan tasks around these objectives to carry out effective Mobile App Usability Testing. For example, Usability Testing scenarios like registration, login, navigation, etc.
  • Test documentation: It’s vital to have test documentation like post-test questionnaires and consent forms when performing Usability Testing for mobile apps. Test documentation can help you identify and fix issues while running Mobile Usability tests.
  • Selecting participants: Select participants based on your target audience for adding value to your product. However, you require additional resources and efforts to get accurate results.
  • Test environment: Select the platform on which you want to run the tests, i.e., in a lab or remotely. You can perform lab testing in a controlled environment, whereas Remote testing is carried out in a cloud-based environment.

Challenges of Mobile App Usability Testing

Following are some of the challenges associated with Mobile App Usability Testing –

  • Target audience: Selecting the right target users for your app might be tedious and time-consuming.
  • Require manual efforts: Mobile App Usability Testing is a type of non-functional testing; therefore, it is time-consuming and requires manual efforts from the QA side.
  • Expensive: Usability Testing is costly as it can extend for a longer time.
  • Execution hiccups: Conducting Usability Testing manually and data analysis takes ample time and effort.
  • Achieving 100% real-user experience is impossible: Since the users are selected randomly to run usability tests, the expected result may be compromised. To achieve 100% real-user experience, all users or participants should give valuable or accurate feedback, which is impracticable to achieve.
