# FastWindow vs Fasting Tracker

The clearest difference is iOS requirement: FastWindow at 15.1 against Fasting Tracker's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. FastWindow sells 1 one-off in-app purchase and Fasting Tracker sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
