# RADD vs Really Bad Chess

The clearest difference is rating: RADD at 4.8 against Really Bad Chess's 3.8. RADD also leads on ads (none vs shown) and review sentiment (81% vs 46%). Really Bad Chess's advantage is ratings volume (1.6K vs 29). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. RADD sells 1 one-off in-app purchase and Really Bad Chess sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
