How do I pair my Suunto EON Steel and Core with Suunto app for iOS?

Learn how to pair your Suunto EON Steel and EON Core dive computer with Suunto app.

Prepare your dive computer for pairing:

If your dive computer has been paired with another mobile app e.g. Suunto Movescount App, unpair your dive computer as follows:

  1. Ensure you have the latest software installed on your dive computer. Please connect your device to DM5 and check if an update is available for your watch.
  2. On your dive computer: Enter the menu and open General > Connectivity > Forget mobile.
  3. On your phone:
    Open Movescount App and tap the watch icon on the top right of the screen. In the watch state view, tap Details in the upper left corner, and then select the Forget button.


  4. In your mobile device settings, go to Bluetooth and remove your watch from the list of connected devices by tapping the info-icon and then Forget this device.


  5. Un-install Movescount App from your phone.
  6. Restart your phone.

Unfortunately, we cannot recommend having both the Suunto app and Movescount app installed on the same phone, as it will cause problems with your dive computer and app connectivity. 

Pairing with Suunto app:

  1. Ensure you use the latest version of the Suunto app. Please check App Store if there is an app update available and install it.
  2. Open the Suunto app on your phone and tap the ‘watch’ icon to enter the Watch view.
  3. When your dive computer appears in the list of devices, tap PAIR, if more than one device is listed, select your dive computer based on the serial number shown at the backside of your product.
