# HIIT vs Interval Timer

The clearest difference is ratings volume: HIIT at 31K against Interval Timer's 296. HIIT also leads on review sentiment (91% vs 73%). Interval Timer's advantage is device support (4 vs 2). On price, rating, update cadence and ads 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 8 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for HIIT against 4.8 for Interval Timer. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 296, so its average is the more settled of the two. Written reviews are what separate them: 91% of HIIT's written reviews are positive against 73% of Interval Timer's.

HIIT ships an update monthly, Interval Timer fortnightly. The most recent releases landed on October 1, 2026 and September 30, 2026 respectively.
