# HIIT Workout Timer vs PeptKit

The clearest difference is device support: PeptKit at 3 against HIIT Workout Timer's 1. PeptKit also leads on iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. HIIT Workout Timer sells 3 in-app purchases, starting at $2.99 per 7 days and PeptKit sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
