ChessveraYour personal chess coach
A chess coach for players without a club.
Most people learn chess alone, playing online with nobody to tell them why a move went wrong. Chessvera reviews your games move by move, explains mistakes in plain words, and turns them into practice.
Coming soon for iPhone and Android. Free to download, no ads. Optional Pro: US$2.99 once, no subscription.
Your f7 pawn was attacked twice and defended only by the king. Better: Qe7 or g6 protects it.
Why Chessvera
Club players have a coach who looks at their games and says "here is where it turned, and here is what to practise". Most of us don't. An engine can tell you a move was bad, but a long line of numbers doesn't teach much. Chessvera uses the Stockfish engine on your phone, then puts what it finds into short, plain reasons and the practice that fits your own mistakes.
Play, or bring a game
Play the built-in bots at the level that suits you, import your recent online games by username, or paste any game in PGN.
See where it turned
The review marks each move, shows the key moments and the better move, and explains it in a sentence or two. When there is no simple reason, it says so and shows you the line instead of making one up.
Practise your own mistakes
Positions where you went wrong come back as puzzles until you find the move. Your training plan and puzzles follow the patterns that cost you most.
What's inside
Simple on purpose: a few things done carefully, not a hundred menus.
A coach while you play
Play Stockfish bots from beginner level up. In Practice mode the coach checks each move, can show a hint or the threat you missed, and lets you take a move back. Challenge mode turns hints off.
Free full game review
Accuracy, an evaluation graph, key moments, arrows for the better move and the strongest reply, and a plain-English reason for each mistake. Moves can be written in plain words ("knight takes on f7") instead of chess notation.
Retry your mistakes
Your own blunders become puzzles. Missed ones come back later, so the lesson actually sticks.
Puzzles that teach
A daily puzzle, training by theme, and Rush against the clock, drawn from a large open database of real-game puzzles.
Lessons and openings
Short fundamentals lessons, endgame drills with a coach, and opening courses that explain the ideas behind the moves, then drill them with spaced repetition.
Your online games
Import the games you played online by username, or paste a game. Connect your account on a free, open-source chess server to play real opponents, or watch top games live.
