Nevermind Support for Apple Watch

Nevermind supports the Apple Watch on all currently available platforms—including Mac and Windows (both the “Flat Screen” version and the virtual reality adaptation).

To use the Apple Watch as a sensor

  • Download the iPhone Nevermind Companion App
    IMPORTANT: As with all Apple Watch apps, an iPhone 5 or later is required.

  • Make sure that the Apple Watch app installs alongside it. You may need to go into “Watch” app on your phone to ensure that it has permission to install to your watch.

  • Ensure that the iPhone Nevermind Companion App and the machine upon which Nevermind is running are both on the same network.

  • Launch the app from your phone. Make sure to enable Read Heart Rate data when it asks.

  • Open up the app on the Watch (if it didn’t open automatically).

  • Give the Watch app a few moments to start reading your heart rate. You should see it update on the phone shortly thereafter.

  • Launch Nevermind from your Mac or Windows machine.

Within the Game

Once the Apple Watch connects to Nevermind, you may need to navigate to the Options screen and switch to [Companion] from [Affdex]. Affdex Enhance can be turned on or off, however, turning it on may result in a more responsive and accurate feeling biofeedback experience.

For more information about combining Physiological Biofeedback and Emotional Biofeedback, please see

When you are done playing

Press “Stop” on either the iPhone or Watch app and close the iPhone app completely. If you don’t press “Stop,” the Watch app will keep reading your heart rate in the background and, before you know it, drain your watch’s battery power. Closing out the iPhone app will ensure that it can properly reconnect with the game next time you use it.

As with any of our supported sensors, if you have any questions or run into any issues, please email us at!



Some suggestions for using the Apple Watch with Nevermind

  • Start the Nevermind heartrate app on iOS just before you launch the game on OSX or Windows.

  • If playing on Windows, make sure you haven’t started the local Nevermind_Companion executable and that it isn’t running (this companion app runs in the system tray on Windows). The local executable will connect to the game and prevent the iOS app from making their necessary connection.

  • Make sure your iPhone and computer are on the same router/network. This may be more difficult in larger business/college campus settings since more complex network setups will make it more difficult for the iPhone and game to find one another on the local network.

  • Make sure someone else nearby or on the same network is not also playing Nevermind. The iOS iPhone app will connect to the first copy of the game it can find, so having multiple copies running may make it difficult to pair an iPhone with an instance of the game. If you need to run multiple copies of Nevermind with multiple copies of the iOS iPhone app, be sure to make pairs one at a time for best results.
