What to do if you can not log into your profile

Starting in 2023, Cardiogram will now require a subscription to log in and access the features within the app. If you are presented with a paywall and have an active Cardiogram subscription, you may need to relink your subscription to your profile. To do that, please follow the steps from this document: I paid for a subscription but can't access the app.

We are actively investigating an issue affecting access to Cardiogram. Please visit the status page for more information. https://cardiogram.statuspage.io/

When in doubt, login-related issues can usually be resolved by:

  1. Logging out and back in
  2. Force closing the app and re-opening
  3. Clearing the app cache
  4. Re-installing Cardiogram.


For password difficulties, see this password reset guide.


Right now, we only support Google login for Android users. This is what lets us communicate with Wear OS devices and Google Fit for information like steps and sleep. We're working on building out the same log-in methods currently available on iPhone, such as email and password, and making Google Fit integration optional.

If you've ever:

  • Logged in with a different method on iPhone.
  • Or complete a password reset.

Then, for security reasons, to re-use the same email, you will have to:

  1. Log in to your account using your old login method.
  2. Deactivate your old account.
  3. Create a new account using that email.

As always, if you need any help, email us at [email protected] so we can investigate this for you.

If you have a Google login on Android, but are getting the error "That account already exists, but used a different login method" when you attempt to log in with your Google account:

This error occasionally comes up if you attempt a password reset. This can disable your Google login method and switch you to an email+password authentication method; we can quickly reset your Cardiogram login method for you. Please send us an email if needed.
