Read me first: how to test Custom RR and unlock its launch
Monsiu Tech
Custom RR is a free, open-source app that puts the whole Android modding scene in one place: which custom ROMs, recoveries, and Treble GSIs officially support your exact phone, with screenshots, freshness signals, and direct links to the official downloads. No more bouncing between the LineageOS wiki, three Telegram channels, and fourteen browser tabs.
✨ What's inside
- 700+ devices, 18 actively-maintained ROMs, and the major recoveries
- Pick your phone and the app filters to what supports it
- Flashing guides, a Treble & GSI hub, and defunct-project warnings
- Material You theming: no tracking, no ads, no Play Services
🙌 Why you matter
Google requires at least 12 testers staying opted in for 14 days before Custom RR can launch to everyone on the Play Store. By joining and keeping it installed, you directly unlock the public release, and you get the app early.
🚀 How to get it (3 steps)
- Sign in to the Google account you use on your phone.
- Join this Google group —You are currently only viewing it, go back to the previous page and click Join group (viewing is not joining). Here is the link to take you back so you can see the "Join group" button>> https://groups.google.com/u/0/g/custom-rr-play-testers
- Opt in and install:
- Testing opt-in: https://play.google.com/apps/testing/io.github.monsiu.custom_rr
- Get it on the Play Store: https://play.google.com/store/apps/details?id=io.github.monsiu.custom_rr
⚠️ Use the same Google account for all three steps, or Play will say you are not a tester. Access can take a little while to propagate after you join.
💬 Feedback & alternatives
- Prefer not to use Google Play? The APK is on GitHub Releases, and an F-Droid listing is on the way.

Thanks for helping launch Custom RR. Please keep it installed so we hit that 14-day mark together.
