Docs
The nine suite is still under active development. This page only covers installing the apps for now — screenshots, keypad references, and settings documentation will get their own page per app as each gets closer to a first release.
Installing
None of the apps are on F-Droid yet. For now, build the one you want from source:
git clone https://git.sr.ht/~timofurrer/nine
cd nine
./gradlew :l9:app:installDebug
Swap :l9:app:installDebug for :c9:app:installDebug to install C9 instead — each app installs independently, so pick just the ones you want.
You'll need a JDK (17 or 21 — newer JDKs aren't yet supported by the Android build tools) and the Android SDK with platform-tools installed. All apps currently target Android 14 (API 34).
A couple of apps need one extra step after installing — for instance, a launcher has to be set as your device's default Home app from Android's own settings. Details for that live with each app's own docs once those exist.
