About

Built for people who train, not people who scroll.

FitnessOS started as one app to replace five: a lifting log, a food tracker, a run tracker, a recovery score and a coach in your pocket. Each one is fast on its own. Together, they finally talk to each other.

Your data stays yours — synced across devices, exportable any time, and never sold.
