Verdict

The call

Fast and Intermittent Fasting both sit at 4.7 stars, but that hides the real split: 75% of Fast's written reviews are positive against 50% of Intermittent Fasting's. Fast also leads on device support (3 vs 1) and ratings volume (3.3K vs 1K). Intermittent Fasting's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (16.0 vs 18.6). On price, rating, ads and in-app purchases there is nothing between them.
