# InterFasting vs Waterfaster

The clearest difference is ads: Waterfaster at none against InterFasting's shown. Waterfaster also leads on rating (5.0 vs 4.8). InterFasting's advantage is ratings volume (360 vs 2) and update cadence (every 4 days vs every 11 days). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. InterFasting sells 5 in-app purchases, starting at $3.99 per month and Waterfaster sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Waterfaster holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: InterFasting has 360 ratings behind it against 2, so its average is the more settled of the two.

InterFasting ships an update every 4 days, Waterfaster every 11 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
