Verdict
The clearest difference is ads: Chess Notation Trainer at none against Chess King's shown. Chess Notation Trainer also leads on update cadence (every 2 days vs every 3 weeks) and review sentiment (100% vs 78%). Chess King's advantage is ratings volume (2.5K vs 16) and rating (4.8 vs 4.5). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Chess King sells 17 in-app purchases, starting at $5.99 per month and Chess Notation Trainer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Chess King holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Chess King has 2.5K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 78% of Chess King's written reviews are positive against 100% of Chess Notation Trainer's, so the app with the better star average is not the one people write more warmly about.
Chess King ships an update every 3 weeks, Chess Notation Trainer every 2 days. The most recent releases landed on September 25, 2026 and September 7, 2026 respectively.
