# HeyFast vs Water Fasting

The clearest difference is ratings volume: HeyFast at 27 against Water Fasting's 4. HeyFast also leads on iOS requirement (15.0 vs 18.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. HeyFast sells 3 in-app purchases, starting at $1.99 per month and Water Fasting sells 2 in-app purchases, starting at $9.99 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 — 4.9 for HeyFast against 5.0 for Water Fasting. That said, the two scores are not equally well evidenced: HeyFast has 27 ratings behind it against 4, so its average is the more settled of the two.

HeyFast ships an update every 2 weeks, Water Fasting every 3 weeks. Both last shipped on October 24, 2026.
