# ChessLine vs PGN Trainer

The clearest difference is rating: PGN Trainer at 5.0 against ChessLine's 4.4. ChessLine's advantage is ratings volume (8 vs 1) and iOS requirement (15.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ChessLine sells 4 in-app purchases, starting at $4.99 per month and PGN Trainer sells 3 in-app purchases, starting at $7.99 per year. Whichever you choose, the download price is not the number that matters.

PGN Trainer holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: ChessLine has 8 ratings behind it against 1, so its average is the more settled of the two.

ChessLine ships an update every 10 days, PGN Trainer every 5 days. The most recent releases landed on November 5, 2026 and November 9, 2026 respectively.
