Finding the right mobile app testing tool is crucial for any app designer aiming to create standout applications. The Userbrain team has rigorously tested a wide array of tools to identify the most effective ones for this purpose. Our focus was on usability, functionality, and the ability to deliver actionable user insights. After a thorough and selective process, we’ve compiled a list of the 10 best mobile app testing tools that every app designer should consider. Most of what’s below are UX and usability testing platforms; a few are crowdtesting or QA testing services that solve a different problem but get lumped into the same searches. We’ve grouped them so you can tell which is which at a glance. If you’re after usability testing tools beyond mobile apps specifically, see our roundup of free usability testing tools, and for a deeper walkthrough of testing on-device, read our guide to mobile usability testing. These tools are not just about app testing; they’re about empowering designers and product managers to build apps that excel in user experience and performance.

How We Evaluated These Tools

We narrowed this list to tools a designer or product manager could realistically evaluate and start using without a lengthy procurement process. Here’s what we weighed for each one:

• Ease of use: Can someone without a research background set up a test and make sense of the results, or does it need a dedicated researcher or QA engineer to run?
• Device and OS coverage: Does the tool test on real iOS and Android devices, or mostly emulators and desktop browsers rendering a mobile view?
• Pricing transparency: Is pricing published, or does every plan route to a sales call? We’ve noted this for each tool below.
• Tester recruitment vs. bring-your-own-testers: Does the tool supply its own participant pool, let you invite your own users, or both?
• Turnaround speed: How fast can you expect results back, from setting up a test to watching a completed session?

UX and Usability Testing Platforms

These are the tools built for watching real people use your app and surfacing usability issues, not for running automated QA scripts against it. (If that distinction is exactly what brought you here, jump to the FAQ below on usability testing tools vs. test automation tools.)
