# Interval Timer vs Round

The clearest difference is rating: Interval Timer at 4.7 against Round's 4.0. Interval Timer also leads on ratings volume (3.6K vs 1).

Both are free to download. Interval Timer sells 10 in-app purchases, starting at $1.99 per month. Round asks for nothing beyond the download.

Interval Timer holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Interval Timer has 3.6K ratings behind it against 1, so its average is the more settled of the two.

Interval Timer ships an update every 4 weeks, Round every 8 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
