ReceptionRating · Positive reviews · Number of ratings

Chronofit holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: intervals has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 75% of Chronofit's written reviews are positive against 100% of intervals's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Chronofit ships an update monthly, intervals every 5 weeks. The most recent releases landed on September 19, 2026 and July 4, 2026 respectively.
