Can i use sleep tracking using a LG G smartwatch (no built in speaker) by using the sonar instread of the accelerometer?

I am curious if sonar is compatible with my smart watch and if is a better option.
Also when using a smart watch, the noise recording is using my watch mic or the phones. Most times i don t keep the phone nearby
