Why don't I see sleep data?

Apple Watch and wearOS users

To see sleep data in Cardiogram, the best thing to do is to use a third-party app that tracks and shares sleep data to your Apple Health or Google Fit app. Cardiogram will then be able to retrieve and display when you slept.

  1. Open the App Store or Google Play.
  2. Search for sleep tracking apps. Some options are Pillow, Sleep for Android, and SleepCycle.
  3. Grant any necessary permissions and install it. 
  4. Make sure that you've set up the app to add data to Apple Health or Google Fit. For example, for Sleep for Android, go to Settings > Services > Google Fit and then follow the instructions on screen.

For Apple Watch users, Cardiogram receives sleep data directly from the "Health" app, so make sure that you have sleep data being added there. To do this, open "Health" > "Show All Health Data" > "Sleep Analysis" > Scroll to bottom > "Show All Data" and confirm that your sleep data is being tracked. 

Then confirm that "Cardiogram" is turned ON (green) under "Health" > "Show All Health Data" > "Sleep Analysis" > Scroll to bottom > "Data Sources & Access".
