Verdict

The call

Intermittent Fasting and Intermittent both sit at 5.0 stars, but that hides the real split: 100% of Intermittent Fasting's written reviews are positive against 50% of Intermittent's. Intermittent Fasting also leads on monetization model (ad-supported vs freemium) and iOS requirement (15.0 vs 17.6). Intermittent's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 weeks). On price, rating, ratings volume and in-app purchases there is nothing between them.
