# Clock in with the mobile app

> Use the Odin mobile app to clock in and out of jobsites

The Odin mobile app lets workers clock in and out of jobsites from their phone. Workers must have completed [onboarding](/onboard-workers/onboarding-workflow) and downloaded the Odin app before they can clock in. When a worker clocks in, Odin records the access event and verifies that the worker meets the site's [access requirements](/control-access/restrict-access).

## Clock in

Open the Odin app and select the jobsite from the list. Jobsites are listed alphabetically, so workers assigned to multiple jobsites may need to scroll to find the correct one. Tap **+ Clock In**, confirm your details, and select **Continue**. The app displays your clocked-in time and duration on site.

## Clock out

From the jobsite screen, tap **Clock Out**, confirm your details, and select **Continue**.

<Note>
  Workers cannot clock in to a new jobsite if they are still clocked in at another site. If geofencing is enabled, the worker must be physically on site to clock out. In either case, a jobsite admin can resolve this by [manually recording an access event](/control-access/clocking-worker-in-out) to clock the worker out of the previous site.
