# Funxtion vs Muscle

The clearest difference is ads: Funxtion at none against Muscle's shown. Muscle's advantage is update cadence (fortnightly vs every 20 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Funxtion ships an update every 20 months, Muscle fortnightly. The most recent releases landed on September 10, 2026 and May 18, 2026 respectively.
