Chessis: Chess Analysis

Chessis is a powerful chess analysis app for Android that transforms every game into a learning opportunity. With the latest Stockfish engine, it provides a full game report highlighting blunders, missed wins, and best moves, explaining not just where you went wrong but why. Trusted by over 1,000,000 players, it offers a coach-like review with accuracy scores, estimated rating, and phase-by-phase breakdowns.

The app includes key moments that decided the game, explained in plain words, and move badges from Brilliant to Blunder. The 'Why Blunder?' feature shows the idea you missed directly on the board, and Retry Mistakes lets you replay critical moments to find better moves. You can analyze games from Chess.com and Lichess, import PGN files, or scan a board with your camera.

Play against human-like bots with different styles at every level, with blunder alerts, hints, and takebacks. Learn openings and traps with comprehensive guides and trap training. Powerful analysis tools include Stockfish 18, multiple engine lines, threat arrows, board editor, games database, Chess960 support, and engine vs. engine matches. It also works with Chessnut electronic boards.

Most features are free, with Chessis Pro offering unlimited analysis, deep analysis with higher depth and NNUE, unlimited engine lines, mistake alerts, 'Why Blunder' lines, and no ads. With beautiful board themes, 14 languages, and Google Drive backup, Chessis is a complete chess improvement companion.
