Frequently Asked Questions

Got questions about the 14-day 20-tester rules? Find the answers below.

How does the 14-day closed testing rule work?
Google Play Console requires at least 20 testers to be opted into your closed testing track and run your app daily for 14 consecutive days. If any tester drops out, the 14-day timer might reset, which is why mutual swap trades are the safest method to keep testers engaged.
Are the testers real users?
Yes, absolutely. 12 Tester is a peer-to-peer community of real Android developers and creators who trade testing slots. You test their apps, and they test yours using their active personal Google accounts.
How does the anti-cheat system protect me?
Our system logs verification sessions using a 20-second active foreground timer and a duplicate device fingerprint checker. This prevents fraud, bots, or testers trying to verify multiple apps on the same physical device.
