Mangus: Chess Coach

Mangus turns your chess.com games into a coach. Type your username and it pulls your recent games and analyzes every move with Stockfish — right on your phone, no account and no servers. • See each move graded — best, inaccuracy, mistake, blunder — with the win% it cost you. • Tap "Show best move" at any position to see what you should have played. • Understand why you lost each game — the one move that actually decided it. • Spot your patterns across games: hung pieces, allowed tactics, where your blunders happen. • Per-game accuracy and an estimate of how strong you played. Everything runs on-device. Your games, coached.
