# 1Timer vs Interval Timer

The clearest difference is ads: Interval Timer at none against 1Timer's shown. 1Timer's advantage is ratings volume (1.2K vs 25) and iOS requirement (15.0 vs 26.0). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. 1Timer sells 5 in-app purchases, starting at $0.99 per 7 days and Interval Timer sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for 1Timer against 4.6 for Interval Timer. That said, the two scores are not equally well evidenced: 1Timer has 1.2K ratings behind it against 25, so its average is the more settled of the two. Written reviews are what separate them: 81% of 1Timer's written reviews are positive against 86% of Interval Timer's.

1Timer ships an update every 6 weeks, Interval Timer every 3 weeks. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
