What is AthleteOS?
AthleteOS is where a gym plans and follows the training of its clients. Coaches build workouts, schedule them for their clients and follow them live. Clients see their workouts on their phone and fill in what they did, set by set.

Two apps in one
AthleteOS has two sides, each with its own sign-in.
| For | Where | What they do | |
|---|---|---|---|
| The coach app | Coaches and admins | /login, on a computer or a tablet | Manage clients, plan sessions, build workouts, run classes, follow sessions live |
| The client app | Your clients | /athlete/login, on their phone | See their sessions, fill in their sets, book sessions and classes, follow their progress |
The sign-in page has a switch between Coach and Athlete, so everyone lands on the right side.


Who can do what
There are two kinds of staff accounts.
- Coach: works with clients, sessions, classes, workouts, exercises and the live view. Every coach sees every client of the gym.
- Admin: everything a coach does, plus the coaches, the settings of the gym, the gym tablets, the reports and the subscription.
Your clients have their own accounts in the client app. They only ever see their own sessions and data.
TIP
The first account of a gym is an admin. Admins can give admin rights to other coaches. See Coaches and rights.
What your plan includes
Some features depend on the plan of your gym. If a menu item is missing, it's usually because your plan doesn't include it.
