It may happen sometimes that the health band links with the phone or some other apps, and this disables the connection between Helo app and device.
- Open the phone's Settings.
- Tap Connections.
- Tap Bluetooth.
- Tap the Settings icon next to the health band name.
- Tap Unpair.
- Log into the Helo app again.
- Go to the “Device” page and choose “Health Band”.
- Now search for your device and link it back to the app.
