APPLE WATCH AND SIRI Start and finish a fast from your Apple Watch. Your session syncs with your paired iPhone when connectivity is available. Tap the watch dial to open its controls.

The stages are general estimates based on elapsed time, not measurements of your metabolism or guarantees of a health result. PRIVATE AND PERSONAL Your fasting records are stored locally on your devices. The app does not collect or sell your fasting data. Paired iPhone–Watch syncing and optional Siri features use Apple system services; details are in the privacy policy. Choose light or dark appearance and your preferred accent color.

Verdict
Simple Fasting App and Fasty both sit at 4.5 stars, but that hides the real split: 77% of Simple Fasting App's written reviews are positive against 8% of Fasty's. Simple Fasting App also leads on in-app purchases (none vs 3) and update cadence (every 6 weeks vs every 9 months). Fasty's advantage is ratings volume (1.5K vs 44). On price, rating, ads and device support 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. Fasty sells 3 in-app purchases, starting at $9.99 per 7 days. Simple Fasting App asks for nothing beyond the download.
Fasty holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Fasty has 1.5K ratings behind it against 44, so its average is the more settled of the two. Written reviews complicate that: 77% of Simple Fasting App's written reviews are positive against 8% of Fasty's, so the app with the better star average is not the one people write more warmly about.
Simple Fasting App ships an update every 6 weeks, Fasty every 9 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
