# Interval Timer vs Round Timer

The clearest difference is ads: Round Timer at none against Interval Timer's shown. Round Timer also leads on monetization model (free vs free with in-app purchases) and update cadence (every 2 weeks vs every 2 months). Interval Timer's advantage is review sentiment (84% vs 67%) and ratings volume (246 vs 14). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Interval Timer sells 1 one-off in-app purchase and Round Timer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Interval Timer against 4.9 for Round Timer. That said, the two scores are not equally well evidenced: Interval Timer has 246 ratings behind it against 14, so its average is the more settled of the two. Written reviews are what separate them: 84% of Interval Timer's written reviews are positive against 67% of Round Timer's.

Interval Timer ships an update every 2 months, Round Timer every 2 weeks. The most recent releases landed on September 28, 2026 and August 23, 2026 respectively.
