ReceptionRating · Positive reviews · Number of ratings

Interval Timer X Workout Timer holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Interval Timer X Workout Timer has 686 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of Timeline's written reviews are positive against 94% of Interval Timer X Workout Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Timeline ships an update every 22 months, Interval Timer X Workout Timer every 6 weeks. The most recent releases landed on September 22, 2026 and September 29, 2026 respectively.
