# Zero vs Fasting Tracker

The clearest difference is update cadence: Zero at every 2 weeks against Fasting Tracker's every 12 months. Zero also leads on ratings volume (445K vs 12) and chart position (#105 vs unranked). 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 sells 3 in-app purchases, starting at $4.99 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 Zero against 4.9 for Fasting Tracker. That said, the two scores are not equally well evidenced: Zero has 445K ratings behind it against 12, so its average is the more settled of the two.

Zero ships an update every 2 weeks, Fasting Tracker every 12 months. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
