# ThinkAutism vs SenseToKnow

The clearest difference is rating: ThinkAutism at 4.0 against SenseToKnow's 3.0. ThinkAutism also leads on iOS requirement (11.0 vs 14.0). SenseToKnow's advantage is update cadence (monthly vs every 21 months) and review sentiment (25% vs 0%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ThinkAutism holds the better App Store score, 4.0 against 3.0. Both are backed by a comparable volume of ratings — 8 and 10 respectively. Written reviews complicate that: 0% of ThinkAutism's written reviews are positive against 25% of SenseToKnow's, so the app with the better star average is not the one people write more warmly about.

ThinkAutism ships an update every 21 months, SenseToKnow monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
