# Intermittent Fasting vs Fasti

The clearest difference is update cadence: Intermittent Fasting at every 3 weeks against Fasti's every 4 months. Fasti's advantage is iOS requirement (16.4 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Intermittent Fasting sells 1 one-off in-app purchase and Fasti sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Intermittent Fasting ships an update every 3 weeks, Fasti every 4 months. The most recent releases landed on October 24, 2026 and October 6, 2026 respectively.
