# Interval Timer vs Round

The clearest difference is rating: Interval Timer at 4.8 against Round's 4.0. Interval Timer also leads on ratings volume (297 vs 1) and iOS requirement (15.0 vs 17.2). Round's advantage is in-app purchases (none vs 7) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Interval Timer sells 7 in-app purchases, starting at $3.99 per month. Round asks for nothing beyond the download.

Interval Timer holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Interval Timer has 297 ratings behind it against 1, so its average is the more settled of the two.

Interval Timer ships an update fortnightly, Round every 8 days. The most recent releases landed on November 2, 2026 and October 31, 2026 respectively.
