Verdict

The call

The clearest difference is in-app purchases: Simple Fasting App at none against FastHabit Intermittent Fasting's 3. Simple Fasting App also leads on review sentiment (77% vs 58%). FastHabit Intermittent Fasting's advantage is ratings volume (14K vs 49) and rating (4.8 vs 4.5). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

FastHabit Intermittent Fasting holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: FastHabit Intermittent Fasting has 14K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 58% of FastHabit Intermittent Fasting's written reviews are positive against 77% of Simple Fasting App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FastHabit Intermittent Fasting ships an update monthly, Simple Fasting App every 6 weeks. The most recent releases landed on November 10, 2026 and November 8, 2026 respectively.
