ReceptionRating · Positive reviews · Number of ratings

Interval Timer holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 73% of Interval Timer's written reviews are positive against 100% of Gustav Workout Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Interval Timer ships an update every 9 days, Gustav Workout Timer monthly. The most recent releases landed on October 12, 2026 and October 1, 2026 respectively.
