# Fallacy vs OINOS

The clearest difference is rating: OINOS at 5.0 against Fallacy's 4.5. OINOS also leads on monetization model (free vs free with in-app purchases). Fallacy's advantage is ratings volume (58 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Fallacy sells 6 in-app purchases, starting at $6.99 per 7 days and OINOS sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

OINOS holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Fallacy has 58 ratings behind it against 1, so its average is the more settled of the two.
