# BehaviorSnap vs TallyFlex

The clearest difference is price: TallyFlex at Free against BehaviorSnap's $9.99. TallyFlex also leads on review sentiment (64% vs 47%). BehaviorSnap's advantage is rating (4.5 vs 4.3) and chart position (#195 vs unranked). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

TallyFlex is free to download; BehaviorSnap costs $9.99 up front. BehaviorSnap sells 10 in-app purchases, starting at $2.99 per month and TallyFlex sells 2 in-app purchases, starting at $27.99 per month. Whichever you choose, the download price is not the number that matters.

BehaviorSnap holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 415 and 87 respectively. Written reviews complicate that: 47% of BehaviorSnap's written reviews are positive against 64% of TallyFlex's, so the app with the better star average is not the one people write more warmly about.

BehaviorSnap ships an update every 3 weeks, TallyFlex every 2 weeks. Both last shipped on September 24, 2026.
