# i.Timer vs Interval Timer HIIT Workout

The clearest difference is review sentiment: i.Timer at 91% against Interval Timer HIIT Workout's 67%. i.Timer also leads on iOS requirement (16.0 vs 18.0). Interval Timer HIIT Workout's advantage is rating (4.9 vs 4.7) and ratings volume (311 vs 29). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. i.Timer sells 1 one-off in-app purchase and Interval Timer HIIT Workout sells 5 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Interval Timer HIIT Workout holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Interval Timer HIIT Workout has 311 ratings behind it against 29, so its average is the more settled of the two. Written reviews complicate that: 91% of i.Timer's written reviews are positive against 67% of Interval Timer HIIT Workout's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. Both last shipped on September 21, 2026.
