# Zero vs Intermittent Fasting Tracker

Zero and Intermittent Fasting Tracker both sit at 4.8 stars, but that hides the real split: 73% of Intermittent Fasting Tracker's written reviews are positive against 32% of Zero's. Intermittent Fasting Tracker also leads on iOS requirement (15.5 vs 17.0). Zero's advantage is ads (none vs shown) and ratings volume (445K vs 29K). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Zero sells 10 in-app purchases, starting at $9.99 per month and Intermittent Fasting Tracker sells 14 in-app purchases, starting at $4.49 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 Zero against 4.9 for Intermittent Fasting Tracker. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 29K, so its average is the more settled of the two. Written reviews are what separate them: 32% of Zero's written reviews are positive against 73% of Intermittent Fasting Tracker's.

Zero ships an update every 2 weeks, Intermittent Fasting Tracker every 8 days. Both last shipped on October 28, 2026.
