# Fallacy vs Think Again

The clearest difference is rating: Fallacy at 4.5 against Think Again's 3.5. Fallacy also leads on review sentiment (76% vs 50%) and ratings volume (57 vs 2). Think Again's advantage is monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Fallacy sells 4 in-app purchases, starting at $6.99 per 7 days and Think Again sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Fallacy holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Fallacy has 57 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 76% of Fallacy's written reviews are positive against 50% of Think Again's.

Fallacy ships an update fortnightly, Think Again every 2 months. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
