PeerPlay
On October 21, 2026 I published a post arguing that testing 12 other apps for Google Play's 14-day rule is worth the time, partly because it is a free lesson in what your own users will feel.
On Indie Hackers, a reader replied with the part I had skipped. The lesson only pays off if the notes get written down. Twelve apps seen for two weeks is a lot of observation, and it evaporates by day 15 unless you keep a simple log. Then the reader showed exactly what that log should look like, and added a second idea for your own testers. Both are good enough to deserve their own post.
Three lines per app
For each app you test in a swap, write one line for each of these:
What the first screen promised. Not what the store listing said, but what the very first screen told you the app would do for you.
What the first action asked of you. Sign in, grant a permission, fill a form, pick a plan. This is where many apps quietly lose people.
The moment you nearly closed it. This is the line almost nobody writes down, and it is the most valuable one. A slow screen, a confusing button, an ad, a wall of text. If it nearly lost you, a doing-a-favor tester, it will lose a real user.
Why it works
One app's notes are an opinion. Twelve apps' notes are a pattern. After a week of the same three lines, the same three or four problems show up again and again across different apps, as the reader put it. Those are the ones worth checking in your own onboarding before you apply for production.
It also costs almost nothing. You are already opening each app every day for 14 days. On the first day, take a minute per app to write the three lines. Add to the third line whenever something makes you want to leave.
One question for every tester
The second idea flips it around. When your swap partners test your app, send each of them the same short question. The reader's example was: "What did you expect to happen after the first tap?"
Twelve free-form reviews are hard to compare. One tester writes about colors, another about a crash, a third says it looks fine. Twelve answers to one identical question line up side by side, and if eight of them describe something different from what your app actually does, you have found your biggest problem in one afternoon.
Keep it to one question, maybe two. Ask it once, around the middle of the test, when testers have used the app a few times but still remember their first impression. And because Google's production application asks what you learned from testing and what you changed, a clear pattern from one question, plus the change you made because of it, is exactly the kind of answer you want to give.
What PeerPlay does today, honestly
The reader also asked whether PeerPlay gives testers any structure for feedback. The honest answer is not yet. Each app card has a "Send feedback" button with a simple "Did you find any bugs?" prompt, and when a developer marks a piece of feedback as resolved, the tester gets a small coin bonus. There is no shared question set.
I noted "what did you expect to happen after the first tap?" as a candidate for an optional prompt. Until something like that exists, nothing stops you from asking it yourself. Send it to your partners in the same message where you share your opt-in link, and keep your own three-line log for theirs. The swap stays the same 14 days. You just get far more out of it.
FAQ
What should I write down when testing other developers' apps?
Three lines per app: what the first screen promised, what the first action asked of you, and the moment you nearly closed it. Patterns across apps show you what to fix in your own onboarding.
What question should I ask my closed testers?
One short question, the same for everyone, such as "What did you expect to happen after the first tap?". Identical answers are easy to compare, unlike free-form reviews.
When should I ask testers for feedback during the 14 days?
Around the middle of the test, when testers have used the app a few times but still remember their first impression.
Does PeerPlay have a feedback form for testers?
Each app card has a "Send feedback" button with a "Did you find any bugs?" prompt. There is no shared question set yet, so ask your own question directly.
