# HIIT vs Simple Training Timer

The clearest difference is ratings volume: HIIT at 31K against Simple Training Timer's 63. HIIT also leads on review sentiment (91% vs 70%) and rating (4.8 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. HIIT sells 11 in-app purchases, starting at $2.99 per 7 days and Simple Training Timer sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

HIIT holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: HIIT has 31K ratings behind it against 63, so its average is the more settled of the two.
