# Interval Timer vs Intensity+

The clearest difference is rating: Interval Timer at 4.9 against Intensity+'s 4.4. Interval Timer also leads on ratings volume (246 vs 7) and iOS requirement (13.0 vs 18.0). Intensity+'s advantage is in-app purchases (none vs 1) and update cadence (monthly vs every 2 months). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Interval Timer sells 1 one-off in-app purchase. Intensity+ asks for nothing beyond the download.

Interval Timer holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Interval Timer has 246 ratings behind it against 7, so its average is the more settled of the two. Written reviews split almost evenly too, at 84% and 83% positive.

Interval Timer ships an update every 2 months, Intensity+ monthly. The most recent releases landed on September 23, 2026 and June 26, 2026 respectively.
