What you need to know about RapidUsertests for smartphones and tablets

Our testers use the RapidTester app for mobile RapidUser tests. This is what it looks like from a tester's perspective.

RapidUsertests can be performed not only on desktop computers, but also on smartphones and tablets. Moreover, you can test not only websites, but also apps. Here we explain what you need to keep in mind when creating and conducting remote mobile usability tests.

1. Choose test devices

When booking a test, you first select how many testers should participate on which devices. Here you can find our tips for selecting the right sample size.

You can also book cross-device tests, in which the same test tasks are performed on all devices. If you want the tasks to be different on the various devices, simply book a separate test for each device.

In this step, you also select on which operating system (Android or iOS) the tests should take place. If you select "any", the testers who accept the test invitation first will take part, regardless of the operating system. In this case, an even distribution of operating systems is therefore not guaranteed. If an even distribution is important to you, then book a separate test for each operating system. We can then combine the different test variants into one test.

The next step is to choose your target group. You can find our tips here.

2. Define Test Object (Unmoderated Tests)

Mobile Website

If you want to test a mobile website, simply enter the URL in the corresponding field:

We then automatically convert the URL to a short link to make it easier for testers to type in their mobile browser.

If you want to test an app that's already been released, just enter the store link.


You can also have your prototype tested on a mobile device.

Share the prototype with a URL from Invision, Figma, etc. To prevent the annoying address bar from always showing, ask the tester to add the page to Home and then re-launch from there.

Unpublished App

This is how you test app prototypes and apps that are unpublished:

Android apps: Provide the link to the APK file.

iOS apps: Provide the tester with a public link from Testflight.

You can find our best practices for writing test tasks here.

3. Test Execution

Testers use our RapidTester app for both unmoderated and moderated tests and interviews.

As a moderator, you do NOT need this app. You can simply carry out the test on your laptop.

Here you can read more about the app and see the tests from a tester's point of view.

In unmoderated tests the testers are switching back and forth between the RapidTester app and the test website/app.

Therefore, keep your tasks short and precise.

This will ensure that the testers answer all your questions.

Important for moderated test

In moderated tests, the test subjects are initially placed in a waiting room. Once the test has started, you can send them the link to the website or app to be tested via the chat. (For interviews without a test object, you can of course skip this step).

This is what it looks like from a tester's perspective:


And now: Happy testing!

Optimize the UX of your mobile website or app!
