Verdict
The clearest difference is review sentiment: Null Fasting at 100% against YABA's 67%. Null Fasting also leads on update cadence (weekly vs every 4 weeks). YABA's advantage is rating (4.7 vs 4.5) and device support (3 vs 1). 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. Neither carries in-app purchases, so what you see is what you pay.
YABA holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 2 and 6 respectively. Written reviews complicate that: 100% of Null Fasting's written reviews are positive against 67% of YABA's, so the app with the better star average is not the one people write more warmly about.
Null Fasting ships an update weekly, YABA every 4 weeks. The most recent releases landed on September 10, 2026 and July 4, 2026 respectively.
