# Fallacy vs ScratchGuide

The clearest difference is rating: ScratchGuide at 5.0 against Fallacy's 4.5. ScratchGuide also leads on review sentiment (100% vs 77%). Fallacy's advantage is ratings volume (58 vs 4) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Fallacy sells 6 in-app purchases, starting at $6.99 per 7 days and ScratchGuide sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ScratchGuide 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 4, so its average is the more settled of the two. Written reviews point the same way: 77% of Fallacy's written reviews are positive against 100% of ScratchGuide's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 12, 2026 and October 3, 2026 respectively.
