Chess DNA turns every game you play into progress. Connect your chess.com or Lichess account and Maya, your AI chess coach, reviews each game seconds after it ends: the moment it turned, why it happened, and the move that would have saved it. YOUR CHESS DNA Eight skills scored from your real games: Openings, Tactics, Defense, Positional play, Endgames, Calculation, Time management and Resilience. See your strengths, your leaks, and exactly what to fix first. EVERY MOVE, EXPLAINED Stockfish finds the best move. Maya tells you why, in plain words, in your language. Key moments, missed tactics and the patterns that keep costing you games are marked for you. REPLAY YOUR MISTAKES Step back into your own lost positions, rewound to the move before it broke, and find the save this time. Every drill comes from a game you actually played. A TRAINING PATH BUILT FROM YOUR LEAKS Maya turns each weakness into a five-minute drill and re-orders your path after every game, so today's step is always the one that matters most. PLAY THE COACH WHO KNOWS YOU Play a full game against Maya at your own rating. She flags every move that drops material, live, while you play. SHARE YOUR BEST MOMENTS Biggest scalp, longest streak, cleanest win. Every milestone becomes a card you can share in one tap.

Verdict

The call

The clearest difference is ads: Chess DNA at none against Chess Prep Pro Openings's shown. Chess DNA also leads on review sentiment (100% vs 75%) and monetization model (free vs free with in-app purchases). Chess Prep Pro Openings's advantage is device support (3 vs 1) and ratings volume (22 vs 6). On price, rating, update cadence and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Chess Prep Pro Openings holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 22 and 6 respectively.
