# HIIT vs Interval Timer

The clearest difference is ads: Interval Timer at none against HIIT's shown. Interval Timer also leads on rating (5.0 vs 4.8) and review sentiment (100% vs 91%). HIIT's advantage is ratings volume (31K vs 3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. HIIT sells 11 in-app purchases, starting at $2.99 per 7 days and Interval Timer sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Interval Timer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 91% of HIIT's written reviews are positive against 100% of Interval Timer's.

HIIT ships an update monthly, Interval Timer every 3 weeks. The most recent releases landed on September 26, 2026 and June 5, 2026 respectively.
