ReceptionRating · Positive reviews · Number of ratings

Forme Fasting Timer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cronometer has 99K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 69% of Cronometer's written reviews are positive against 0% of Forme Fasting Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cronometer ships an update weekly, Forme Fasting Timer every 2 weeks. The most recent releases landed on October 15, 2026 and September 30, 2026 respectively.
