# Water Fasting vs SleepTonic

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.

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.
