Explore Airplane Mode

You can control Bluetooth transmission between your ring and phone with Oura’s Airplane Mode feature.

Enabling Airplane Mode disables the ring’s Bluetooth temporarily. Although your ring continues to monitor your body signals for up to seven days while in Airplane Mode, it will not sync with your phone until you disable it.

Enabling and Disabling Airplane Mode

To enable Airplane Mode, tap the ring icon (two circles) in the top right-hand corner of your home tab and switch the “Ring airplane mode” toggle to on.

Airplane Mode will disable syncing until the next time you charge your ring.

To disable Airplane Mode:

  1. Ensure Bluetooth is enabled on your device.
  2. Connect your ring to its charger and keep your phone nearby.
  3. Wait for the app and ring to automatically reconnect.

Upon completion of these steps, your ring will import any data that was gathered while Airplane Mode was in effect.

Oura’s Bluetooth Profile

Oura has one of the lowest Electromagnetic Field (EMF) transmission profiles among similar consumer electronics. The ring uses Bluetooth for less than 1% of each day. Bluetooth transmissions are disabled when you are inactive or sleeping.

Unless Airplane Mode is enabled, Bluetooth will remain active periodically throughout the day, emitting EMF only when your ring syncs with your phone or during firmware updates.
