Verdict

The call

The clearest difference is review sentiment: Simple Fasting App at 77% against Fasty's 8%. Simple Fasting App also leads on in-app purchases (none vs 3) and update cadence (every 6 weeks vs every 9 months). Fasty's advantage is ratings volume (1.5K vs 46) and rating (4.7 vs 4.5). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Fasty holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Fasty has 1.5K ratings behind it against 46, so its average is the more settled of the two. Written reviews complicate that: 77% of Simple Fasting App's written reviews are positive against 8% of Fasty's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Simple Fasting App ships an update every 6 weeks, Fasty every 9 months. Both last shipped on October 25, 2026.
