# DayBetter vs Kstert

The clearest difference is rating: DayBetter at 3.2 against Kstert's 2.9. DayBetter also leads on ratings volume (1.2K vs 36) and chart position (#76 vs unranked). Kstert's advantage is iOS requirement (12.0 vs 15.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

DayBetter holds the better App Store score, 3.2 against 2.9. That said, the two scores are not equally well evidenced: DayBetter has 1.2K ratings behind it against 36, so its average is the more settled of the two. Written reviews complicate that: 33% of DayBetter's written reviews are positive against 37% of Kstert's, so the app with the better star average is not the one people write more warmly about.

DayBetter ships an update every 10 days, Kstert every 3 weeks. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
