# Fastin vs Intermittent Fasting Tracker

Fastin and Intermittent Fasting Tracker both sit at 4.8 stars, but that hides the real split: 97% of Intermittent Fasting Tracker's written reviews are positive against 33% of Fastin's. Intermittent Fasting Tracker also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (52K vs 10K). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Fastin sells 10 in-app purchases, starting at $4.49 per 7 days and Intermittent Fasting Tracker sells 17 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Fastin against 4.9 for Intermittent Fasting Tracker. That said, the two scores are not equally well evidenced: Intermittent Fasting Tracker has 52K ratings behind it against 10K, so its average is the more settled of the two. Written reviews are what separate them: 33% of Fastin's written reviews are positive against 97% of Intermittent Fasting Tracker's.

Fastin ships an update every 3 weeks, Intermittent Fasting Tracker every 10 days. Both last shipped on October 25, 2026.
