# Interval Timer vs Intervals Pro

The clearest difference is ratings volume: Intervals Pro at 14K against Interval Timer's 534. Intervals Pro also leads on update cadence (every 8 days vs every 4 weeks). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Interval Timer sells 4 in-app purchases, starting at $1.99 per month and Intervals Pro sells 8 in-app purchases, starting at $2.99 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 Interval Timer against 4.8 for Intervals Pro. That said, the two scores are not equally well evidenced: Intervals Pro has 14K ratings behind it against 534, so its average is the more settled of the two. Written reviews are what separate them: 77% of Interval Timer's written reviews are positive against 84% of Intervals Pro's.

Interval Timer ships an update every 4 weeks, Intervals Pro every 8 days. The most recent releases landed on September 17, 2026 and September 24, 2026 respectively.
