# Workout Timer vs SleepStack

The clearest difference is device support: Workout Timer at 3 against SleepStack's 1. Workout Timer also leads on iOS requirement (12.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Workout Timer sells 2 in-app purchases, starting at $3.99 per 7 days and SleepStack sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
