### Proxxi Voltage App

To sync a wristband using the Wearer App, the user just needs to open their Proxxi Voltage App while the wristband is within range.

When on any tab within the app, the mobile device will automatically sync with the wristband to gather any recorded data.

Once synced, a blue checkmark will show on the top section of the home page of the app. The app will wait several minutes before syncing again.

### Proxxi Hub App

To sync a wristband using the Hub App, the user needs to open the "Sync" tab of the Proxxi Hub App while the wristband is within range.

When on the Sync tab, the mobile device will automatically search for all available wristbands within range to gather any recorded data. It will then sync them on-by-on, in the order in which they were located. 

Once this data has synced, the app will wait 15 minutes before attempting to sync the same wristband again. To confirm a wristband has synced, the user can select "Sync History" at the bottom of the Sync tab to review the sync status of all wristbands connected to the app within the past 24 hours.
