Verdict
The clearest difference is review sentiment: Fasting Tracker App at 100% against Fasty's 8%. Fasting Tracker App also leads on update cadence (every 6 days vs every 9 months) and rating (4.9 vs 4.7). Fasty's advantage is ads (none vs shown) and ratings volume (1.5K vs 15). On price, in-app purchases, monetization model 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 and Fasting Tracker App sells 3 in-app purchases, starting at $29.99 per year. Whichever you choose, the download price is not the number that matters.
Fasting Tracker App holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Fasty has 1.5K ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 8% of Fasty's written reviews are positive against 100% of Fasting Tracker App's.
Fasty ships an update every 9 months, Fasting Tracker App every 6 days. Both last shipped on October 25, 2026.
