# Intervals Pro vs RunIntervals

The clearest difference is update cadence: Intervals Pro at every 8 days against RunIntervals's every 3 months. Intervals Pro also leads on ratings volume (14K vs 123). RunIntervals's advantage is iOS requirement (11.3 vs 17.5). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Intervals Pro sells 8 in-app purchases, starting at $2.99 per month and RunIntervals sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Intervals Pro against 4.7 for RunIntervals. That said, the two scores are not equally well evidenced: Intervals Pro has 14K ratings behind it against 123, so its average is the more settled of the two. Written reviews are what separate them: 84% of Intervals Pro's written reviews are positive against 90% of RunIntervals's.

Intervals Pro ships an update every 8 days, RunIntervals every 3 months. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
