Verdict
The clearest difference is ratings volume: Water Fasting at 5 against SleepTonic's 1. SleepTonic's advantage is iOS requirement (16.5 vs 18.0). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Water Fasting sells 2 in-app purchases, starting at $9.99 per month and SleepTonic sells 2 in-app purchases, starting at $2.99 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 — 5.0 for Water Fasting against 5.0 for SleepTonic. That said, the two scores are not equally well evidenced: Water Fasting has 5 ratings behind it against 1, so its average is the more settled of the two.
Water Fasting ships an update every 3 weeks, SleepTonic every 2 weeks. The most recent releases landed on October 31, 2026 and October 7, 2026 respectively.
