# Heatos vs Really Bad Chess

The clearest difference is review sentiment: Heatos at 89% against Really Bad Chess's 46%. Heatos also leads on rating (4.6 vs 3.8) and ads (none vs shown). Really Bad Chess's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (1.6K vs 108). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Heatos sells 3 one-off in-app purchases and Really Bad Chess sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Heatos holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: Really Bad Chess has 1.6K ratings behind it against 108, so its average is the more settled of the two. Written reviews point the same way: 89% of Heatos's written reviews are positive against 46% of Really Bad Chess's.
