Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Null Fasting ships an update weekly, YABA every 4 weeks. The most recent releases landed on September 10, 2026 and July 4, 2026 respectively.
