# Intervals Pro vs Interval Timer

The clearest difference is rating: Intervals Pro at 4.8 against Interval Timer's 3.8. Intervals Pro also leads on ratings volume (14K vs 28) and review sentiment (84% vs 67%). Interval Timer's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (11.0 vs 17.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Intervals Pro sells 8 in-app purchases, starting at $2.99 per month and Interval Timer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Intervals Pro holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Intervals Pro has 14K ratings behind it against 28, so its average is the more settled of the two. Written reviews point the same way: 84% of Intervals Pro's written reviews are positive against 67% of Interval Timer's.

Intervals Pro ships an update every 8 days, Interval Timer weekly. The most recent releases landed on October 18, 2026 and October 3, 2026 respectively.
