# Interval Timer vs Modern Interval Workout Timer

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 (379 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 monthly). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Interval Timer sells 12 in-app purchases, starting at $2.09 per month and Modern Interval Workout Timer sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

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 379 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 97% 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.

Interval Timer ships an update monthly, Modern Interval Workout Timer every 4 days. The most recent releases landed on September 25, 2026 and September 3, 2026 respectively.
