Verdict

The call

The clearest difference is rating: Round Timer at 4.8 against Modern Interval Workout Timer's 3.0. Round Timer also leads on ratings volume (296 vs 1) and device support (4 vs 1).

ReceptionRating · Positive reviews · Number of ratings

Round Timer holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Round Timer has 296 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 73% of Round Timer's written reviews are positive against 100% of Modern Interval Workout Timer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Round Timer ships an update every 3 weeks, Modern Interval Workout Timer every 4 days. The most recent releases landed on September 12, 2026 and September 3, 2026 respectively.
