# MoodStack vs Supplement Tracker

The clearest difference is iOS requirement: MoodStack at 18.0 against Supplement Tracker's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. MoodStack sells 11 in-app purchases, starting at $3.99 per 7 days and Supplement Tracker sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
