# Interval Timer vs Round Timer

The clearest difference is ads: Round Timer at none against Interval Timer's shown. Round Timer also leads on rating (4.9 vs 4.5) and monetization model (free vs free with in-app purchases). Interval Timer's advantage is ratings volume (19K vs 14) and iOS requirement (13.0 vs 15.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and Round Timer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Round Timer holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Interval Timer has 19K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 69% of Interval Timer's written reviews are positive against 67% of Round Timer's, so the app with the better star average is not the one people write more warmly about.

Interval Timer ships an update every 9 days, Round Timer every 2 weeks. The most recent releases landed on September 24, 2026 and August 23, 2026 respectively.
