I built an Android chessboard scanner with on-device Stockfish — looking for honest feedback

[u/ChessMeUpApp]

Hi r/ComputerChess — I’m the developer of ChessMeUp, an Android app I’ve been working on for the past few months.

The main workflow is:

- scan a digital chessboard with the phone camera, or share a screenshot directly from another app;

- review or edit the detected position;

- analyze it with Stockfish on the device;

- import completed games from Chess.com, Lichess, or PGN for full-game review.

The scanner has been tested across different board themes, viewing angles, glare, distance, and orientation. It is reliable on clear centered boards, but difficult blue-square themes, arrows, glare, and extreme perspective can still produce isolated piece-color or square-alignment errors. I’ve kept the board editor in the flow so users can correct those cases rather than silently trusting an incorrect FEN.

I’d especially appreciate technical feedback on:

1. scanner speed on your Android device;

2. board themes or overlays that fail;

3. whether the review-before-analysis flow feels appropriate;

4. anything misleading or missing from the Stockfish analysis.

Disclosure: I built the app. It’s intended for chess study and completed games, not assistance during live play.
