Results: Sonar or Accelerometer

How does one determine if testing was done under accelerometer or sonar?
Need to denote clearly which was active during sleep cycle

You determine that by going into settings, sleep tracking, then sensors and choose accelerometer or sonar. Using sonar the phone sits on your bedside table. Using accelerometer means having the phone on the bed near you. Hope that helps. It would be nice to see some sort of indication on the page where you start tracking though.
