For Lief Pro users, first setup your account (see here) using the same email you used to purchase your Lief on our website or Kickstarter.
Once you're setup, you can navigate to the Lief Login page to access the dashboard.
The Lief records both heart rate and HRV continuously. To access this time series data, click the "Download" button on your Lief Dashboard and you will be emailed a CSV file.
If you are having trouble or need personalized assistance, kindly send a message to the Lief ZenDesk Support Team.
