Chess GM Champion

Chess GM Champion is a complete chess trainer that lives entirely on your
phone. Play against the Stockfish engine — one of the strongest chess engines
in the world — at a strength that matches you, and learn from every game: the
app notices the mistakes you keep repeating and coaches you out of them.
No sign-up, no ads, no internet required.

PLAY YOUR WAY
- Nine difficulty levels from first-game friendly (about 600 Elo) to
grandmaster-level Stockfish strength.
- New to chess? The beginner ladder starts you against a lone king and adds
pieces back one rung at a time — you always play a game you can finish.
- Choose your color, time control, board themes and piece sets. Kid mode
with gentler coaching included.
- Set up any position in the board editor and play or study from there.

A COACH THAT KNOWS YOUR GAME
- Move-by-move coaching explains the ideas behind moves as you play.
- Blundered? Flip the board and see the position through your opponent's
eyes to understand what they saw.
- The app tracks the mistakes you repeat — hanging pieces, missed tactics —
and a "Your Habits" card shows them shrinking as you improve.
- Wrong puzzle answer? You see exactly why it fails, not just that it does.
And any winning move is accepted — checkmate is checkmate.

PUZZLES & LEARNING PATH
- A guided Learning Path of hundreds of checkmate puzzles drawn from
classic training books.
- Spaced repetition brings solved puzzles back just before you would
forget them.
- Daily puzzle streaks, Puzzle Rush, and puzzles grouped by theme.
- Your own blunders become custom puzzles — train on your real games.

TRACK AND CELEBRATE
- An estimated Elo rating that moves with your results, with history graphs,
streaks and stats.
- 15 achievements to unlock, shareable milestone cards, and full game
replays with an evaluation graph.

BUILT FOR EVERYONE
- Spoken moves, large-text mode, color-blind friendly board markers, and
full keyboard play.
- A gentle daily reminder keeps your streak alive (optional).

PRIVATE BY DESIGN
- Works fully offline. The chess engine runs on your device.
- No accounts, no ads, no data collection — nothing leaves your phone.
- Your progress is backed up on-device and survives reinstalling the app.

From your very first game to serious study — powered by the open-source
Stockfish engine.
