# Energy vs Decision Muscle

Both are free to download. Energy sells 1 one-off in-app purchase and Decision Muscle sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Energy ships an update every 3 months, Decision Muscle every 4 days. The most recent releases landed on October 12, 2026 and October 26, 2026 respectively.
