# Intervals Pro vs Just Run

Intervals Pro and Just Run both sit at 4.8 stars, but that hides the real split: 99% of Just Run's written reviews are positive against 84% of Intervals Pro's. Intervals Pro's advantage is update cadence (weekly vs every 3 weeks) and ratings volume (14K vs 1.3K). On price, rating, 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 Just Run sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Just Run holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Intervals Pro has 14K ratings behind it against 1.3K, 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 99% of Just Run's.

Intervals Pro ships an update weekly, Just Run every 3 weeks. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
