# Chess Elo Calculator vs Noctie Chess Trainer

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.

Both are free to download. Noctie Chess Trainer sells 2 in-app purchases, starting at $13.90 per month. Chess Elo Calculator asks for nothing beyond the download.

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.

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.
