# Water Fasting vs AI Water Reminder & Tracker

The clearest difference is iOS requirement: AI Water Reminder & Tracker at 13.0 against Water Fasting's 18.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Water Fasting sells 2 in-app purchases, starting at $9.99 per month and AI Water Reminder & Tracker sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
