Moderated: you are present (in person or on a call), give tasks, watch and ask. Unmoderated: the tester works alone, on their own time, and reports afterwards in writing or by recording.
Comparison
| Moderated | Unmoderated | |
|---|---|---|
| Your time | High: you attend every session | Low: you read results |
| Depth | You can ask "why?" on the spot | Only what the tester wrote down |
| Scheduling | Needs shared time slots | Tester picks the time |
| Setting | Often a lab-like call | Real device, real surroundings |
| Risk | You may influence the person | Unclear answers cannot be probed |
| Best for | Confusing flows, early prototypes | Broad bug hunting, device variety, quick checks |
When to choose which
- Early idea or unclear flow: moderated. You need the "why" and can adjust the task live.
- A build that mostly works and needs bug and device coverage: unmoderated, with a clear structure so answers are comparable.
- Little time, many devices: unmoderated.
- A problem you cannot explain from the written report: follow up with a short moderated call.
You can combine both: unmoderated first to find what breaks, then two or three moderated sessions on the worst spots.
Peer testing as an unmoderated option
On AppReviewX, other developers test your app on their own and send private, structured feedback. That is unmoderated: you do not sit beside them, so clear test notes matter. Use a fixed structure for reports (see bug report template and onboarding questions for testers). One feedback you write earns one credit; new accounts start with 0.
For Google Play there are test groups (12 testers, 14 days in a row, for Android apps) and test packages for apps that are already published.
Limits
Unmoderated testers are not your target users by default; they are fellow developers. Keep interviews or small user tests for questions about your audience. See user interviews for mobile apps.
