# Intervals Pro vs Ultra Intervals Workout Timer

The clearest difference is in-app purchases: Ultra Intervals Workout Timer at none against Intervals Pro's 8. Ultra Intervals Workout Timer also leads on iOS requirement (13.0 vs 17.5). Intervals Pro's advantage is ratings volume (14K vs 4) and rating (4.8 vs 4.5). On price, review sentiment, update cadence 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. Ultra Intervals Workout Timer asks for nothing beyond the download.

Intervals Pro holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Intervals Pro has 14K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 84% of Intervals Pro's written reviews are positive against 89% of Ultra Intervals Workout Timer's, so the app with the better star average is not the one people write more warmly about.

Intervals Pro ships an update every 8 days, Ultra Intervals Workout Timer every 6 days. The most recent releases landed on October 12, 2026 and September 19, 2026 respectively.
