Verdict

The call

The clearest difference is rating: Interval Timer at 4.9 against Modern Interval Workout Timer's 3.0. Interval Timer also leads on ratings volume (246 vs 1) and device support (4 vs 1). Modern Interval Workout Timer's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 months). On price, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Interval Timer holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Interval Timer has 246 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 84% of Interval 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

Interval Timer ships an update every 2 months, Modern Interval Workout Timer every 4 days. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
