# Symbols vs Fallacy

Symbols and Fallacy both sit at 4.6 stars, but that hides the real split: 100% of Symbols's written reviews are positive against 78% of Fallacy's. Symbols also leads on iOS requirement (12.0 vs 15.1). Fallacy's advantage is update cadence (fortnightly vs every 6 weeks) and ratings volume (58 vs 10). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Symbols sells 6 in-app purchases, starting at $3.99 per month and Fallacy sells 6 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Symbols against 4.5 for Fallacy. That said, the two scores are not equally well evidenced: Fallacy has 58 ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 100% of Symbols's written reviews are positive against 78% of Fallacy's.

Symbols ships an update every 6 weeks, Fallacy fortnightly. Both last shipped on October 24, 2026.
