# Pace Calculator vs Interval Timer

The clearest difference is review sentiment: Pace Calculator at 68% against Interval Timer's 21%. Pace Calculator also leads on update cadence (every 5 days vs every 3 months) and iOS requirement (16.0 vs 26.0). Interval Timer's advantage is ads (none vs shown) and rating (4.5 vs 4.3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Pace Calculator sells 1 one-off in-app purchase and Interval Timer sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Interval Timer holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Interval Timer has 534 ratings behind it against 39, so its average is the more settled of the two. Written reviews complicate that: 68% of Pace Calculator's written reviews are positive against 21% of Interval Timer's, so the app with the better star average is not the one people write more warmly about.

Pace Calculator ships an update every 5 days, Interval Timer every 3 months. The most recent releases landed on October 8, 2026 and October 14, 2026 respectively.
