ECG and Sleep Tracking
Our app does not have built-in ECG / EKG functionality and does not measure individual heart rates. We retrieve sleep tracking data directly from the Google Fit, Fitbit, or Garmin Connect apps and show this information in the context of your heart rate. We don’t write any data to Google Fit yet, but stay tuned for updates.

Supported Languages
We currently only offer the app in English.
