# MoodStack vs Supplement Tracker

The clearest difference is monetization model: Supplement Tracker at free against MoodStack's freemium. MoodStack's advantage is update cadence (every 4 days vs fortnightly). 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 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

MoodStack ships an update every 4 days, Supplement Tracker fortnightly. The most recent releases landed on October 1, 2026 and October 14, 2026 respectively.
