# Zero vs Fasting Tracker App

Zero and Fasting Tracker App both sit at 4.8 stars, but that hides the real split: 61% of Fasting Tracker App's written reviews are positive against 32% of Zero's. Fasting Tracker App also leads on device support (4 vs 2) and iOS requirement (13.0 vs 17.0). Zero's advantage is ratings volume (445K vs 866) and update cadence (every 2 weeks vs every 6 weeks). On price, rating, ads 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 Fasting Tracker App sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Zero holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 866, so its average is the more settled of the two. Written reviews complicate that: 32% of Zero's written reviews are positive against 61% of Fasting Tracker App's, so the app with the better star average is not the one people write more warmly about.

Zero ships an update every 2 weeks, Fasting Tracker App every 6 weeks. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
