The Andromeda chess archive on your phone
Andromeda Chess for Android is a native Kotlin app that puts the archive in your pocket. It talks to Andromeda's public JSON APIs directly — no embedded browser — so lists, boards, and analysis feel like a real Android app rather than a wrapped website.
Browse the study players and their games, replay annotated books move by move, and open any position on a full board with Android controls, saved state, and offline-friendly navigation.
Browse study players, their game lists, metadata, and PGN, plus the annotated-book collection.
Open any position on a full board and analyse it with a bundled engine — evaluation and principal variations.
Drive a board on another screen from your phone, or follow along on a linked device.
Point the camera at a printed board to lift the position onto the analysis board. Still experimental.
The app installs from a signed APK hosted here — it is not on the Play Store. Download it, then allow installs from your browser or files app if Android prompts you. Updates are delivered in-app from the same signed source, so future versions install over this one cleanly.
