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: IF has 2.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 61% of IF'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

IF ships an update every 3 weeks, Forme Fasting Timer every 2 weeks. The most recent releases landed on September 22, 2026 and September 11, 2026 respectively.
