How can I integrate my Fitbit data with the app?

Fitbit integration can be enabled by tapping 'More' from the bottom navigation then tapping 'Data Integrations' then toggling Fitbit to On. You can also sync your Fitbit data with Apple Health or Google Fit, which can then be imported into the app. Go to the Integrations screen and enable the Apple Health or Google Fit integration to import your activity, sleep, and heart rate data.
