The first thing to do is make sure you are signed in to your Calm account using the same email address and password you used to sign up for your Calm subscription.
To sign in to the Calm website, click "Log in" in the upper right corner.
To sign in to the Calm app, tap the "More" button in the bottom right corner of the home screen, and select "Profile" in the upper right corner. In the Profile menu, select "Sign up or Log in" and then choose "Log in" at the bottom of the page.
If you do not see the "Sign up or Log in" option, please first log out of your Calm app. To log out, tap the "More" button in the bottom right corner of the home screen and select the gear icon in the upper left corner. Scroll to the bottom of the page and tap "Logout." After logging out please quit the Calm app, then re-launch it. From here, log back in by heading to More > Profile and selecting the option to log in.
If this does not work for you, please make sure that your Calm app is updated to the latest version.
If you have any further trouble accessing Calm's premium content, please write to our support team here and provide a screenshot of the locked content, along with the email address on your Calm account.
