Mystery Customer InsightHow it works
Free user testing and usability testing for indie apps — real people, real devices. No subscriptions, no hidden fees.
1. Submit an app
A developer submits an app for free: app link, target platforms, a test scenario, and a few simple questions.
2. Test on real devices
This is remote user testing: human testers browse open apps and complete the scenario themselves on their own phones and tablets — no facilitator, no session to schedule.
3. Get results
Developers receive real-world usability feedback from real users — answers, comments, and links.
A to-do app · tested on a phone
- Could you add your first task without help?
- Yes — the add button was obvious, first task added in a few seconds.
- Did anything confuse you?
- The due-date picker opened behind the keyboard, so I could not see the day I was choosing.
- Would you use it again?
- Probably, for simple lists.
Tester comment: Smooth overall. The empty first screen could suggest adding a task, so it feels less blank when you open the app.
