# Really Bad Chess vs GPT Chess

The clearest difference is ads: GPT Chess at none against Really Bad Chess's shown. GPT Chess also leads on rating (4.1 vs 3.8) and update cadence (every 9 days vs every 3 weeks). Really Bad Chess's advantage is ratings volume (1.6K vs 16) and review sentiment (46% vs 33%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Really Bad Chess sells 2 one-off in-app purchases 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 3.8. That said, the two scores are not equally well evidenced: Really Bad Chess has 1.6K ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 46% of Really Bad Chess's written reviews are positive against 33% of GPT Chess's, so the app with the better star average is not the one people write more warmly about.

Really Bad Chess ships an update every 3 weeks, GPT Chess every 9 days. The most recent releases landed on September 23, 2026 and August 31, 2026 respectively.
