Most chess apps make you play a machine. Noctie gives you a training partner. Noctie is a premium chess trainer that plays like a human, adapts to your level, and turns every game into focused practice. Play the opening you like, get puzzles from your game, have fun. No weird engine moves, just real games against a realistic opponent, with instant feedback that shows you how to improve on every move. TRAIN AGAINST HUMAN-LIKE AI OPPONENTS Train against a chess AI that adapts to your level and makes natural, human mistakes instead of perfect computer moves. Improve through 25 difficulty levels of humanlike chess bots, from beginner to master. MASTER YOUR OPENINGS THE RIGHT WAY Choose among your favorite chess openings or import your own repertoire, and train against an AI that follows the lines humans actually play. You don't just memorize theory; you learn to play it. GET INSTANT VISUAL FEEDBACK WHILE YOU PLAY See color-coded move-quality feedback the moment you play. Spot tactical mistakes and brilliant moves in real time, so every game teaches you something. SOLVE PUZZLES FROM YOUR ACTUAL GAMES After each game, practice custom chess tactics from the exact positions where you struggled. Your puzzles are saved for spaced-repetition practice, so you never repeat the same mistake twice. SET UP ANY POSITION, STUDY LESSONS & ENDGAMES Use the position builder to set up any chess position, or play scenarios from our instructive lessons — covering everything from positional imbalances to theoretical endgames. Drill king-and-pawn endgames until they're second nature.

Verdict

The call

The clearest difference is rating: Noctie Chess Trainer at 4.7 against Chess Elo Calculator's 3.0. Noctie Chess Trainer also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (640 vs 2). Chess Elo Calculator's advantage is in-app purchases (none vs 2) and review sentiment (100% vs 74%). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Noctie Chess Trainer holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Noctie Chess Trainer has 640 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Chess Elo Calculator's written reviews are positive against 74% of Noctie Chess Trainer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Chess Elo Calculator ships an update every 5 months, Noctie Chess Trainer every 3 weeks. The most recent releases landed on November 3, 2026 and November 12, 2026 respectively.
