# SaltLess vs Sleep Tracker

The clearest difference is iOS requirement: SaltLess at 15.0 against Sleep Tracker's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. SaltLess sells 3 in-app purchases, starting at $0.29 per month and Sleep Tracker sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
