# Interval Timer vs HIIT

The clearest difference is review sentiment: HIIT at 91% against Interval Timer's 69%. HIIT also leads on rating (4.8 vs 4.5). Interval Timer's advantage is update cadence (every 9 days vs monthly) and device support (4 vs 2). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Interval Timer sells 6 in-app purchases, starting at $0.99 per month and HIIT sells 11 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

HIIT holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 19K and 31K respectively. Written reviews point the same way: 69% of Interval Timer's written reviews are positive against 91% of HIIT's.
