  • Go to your device's App Store and search for “Mightier.” Our app is pretty large, so it’s normal for it to take up to 15 minutes to download.


Step 2: Log into the Mightier App

  • Once the download is complete, open the app and log in using the email address and password you created when you purchased Mightier (this is different than your Google account login).
  • If you're having trouble, click here and we will email you a link to reset your password.
  • You can also log into the Mightier app using a one-time login code. To access this feature, click the Settings button in the top right corner of the Parent app. Then, tap "Get a Login Code."


Step 3: Set up the Heart Sensor

  • Before you play, remove the protective sticker.
