About Custom RR
Custom RR is a free, open-source companion app for the Android modding scene. It puts everything in one place: which custom ROMs and recoveries officially support your device, what Treble GSIs you can flash, and where to download them. No more bouncing between the LineageOS wiki, three Telegram channels, a SourceForge folder, and fourteen browser tabs. Features: 18 actively-maintained ROMs (LineageOS, crDroid, PixelOS, Project Elixir, Evolution X, DerpFest, UN1CA, BlissROMs, /e/, GrapheneOS, CalyxOS, DivestOS, RisingOS Revived, VoltageOS, and more), each with description, features, screenshots, and a one-tap link to the official download page.
Privacy and F-Droid
F-Droid builds Custom RR from its published source code and flags anti-features such as ads, tracking or reliance on non-free services.
