Verdict
The clearest difference is review sentiment: FastingCat at 100% against Fasting Tracker's 0%. FastingCat also leads on rating (4.9 vs 3.7) and update cadence (every 6 days vs every 7 months). On price, ads, in-app purchases and monetization model 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. Fasting Tracker sells 2 in-app purchases, starting at $0.99 per 7 days and FastingCat sells 10 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
FastingCat holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: FastingCat has 56 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 0% of Fasting Tracker's written reviews are positive against 100% of FastingCat's.
Fasting Tracker ships an update every 7 months, FastingCat every 6 days. Both last shipped on October 24, 2026.
