Verdict
The clearest difference is ads: Intermittent Fasting at none against FastFlow's shown. Intermittent Fasting also leads on update cadence (every 8 days vs every 4 months). FastFlow's advantage is monetization model (ad-supported vs paid) and device support (3 vs 1). On price, review sentiment and in-app purchases there is nothing between them.
