# ChessPrep vs GPT Chess

The clearest difference is rating: GPT Chess at 4.1 against ChessPrep's 3.0. GPT Chess also leads on ratings volume (16 vs 2). ChessPrep's advantage is update cadence (every 3 days vs every 9 days) and iOS requirement (12.0 vs 16.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. ChessPrep sells 3 in-app purchases, starting at $0.99 per month and GPT Chess sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

GPT Chess holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: GPT Chess has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 33% and 33% positive.

ChessPrep ships an update every 3 days, GPT Chess every 9 days. The most recent releases landed on June 11, 2026 and August 31, 2026 respectively.
