# NoSugar vs Fasting Mastery

The clearest difference is update cadence: Fasting Mastery at every 5 days against NoSugar's every 2 weeks. Fasting Mastery also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18). On price, ads and in-app purchases there is nothing between them.

Both are free to download. NoSugar sells 2 in-app purchases, starting at $4.99 per 7 days and Fasting Mastery sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

NoSugar ships an update every 2 weeks, Fasting Mastery every 5 days. Both last shipped on October 15, 2026.
