Once the ring has been taken to use and is no longer in factory state, you need to connect it to the charger in order to reconnect it with the app again.
- Launch the freshly installed Oura app.
- Sign in using your Oura account details.
- Connect the ring to the charger. Follow the app instructions to pair the ring and the app.
- Wait for your ring and app to connect.
If you're switching phones and installing the app on a new device, please close or delete the app from your previous device before connecting to the new one.
