As a physician that monitors biometric data in my clients, I find the Biostrap to be my recommended device. Several reasons for this and I recently wore both the Biostrap and Fitbit for 14 days to compare results and check against my medical measurements in office.

Just finishing up 5 days of use and I couldn't be more satisfied. It has actually surprised me, because I held off buying the Biostrap thinking that it wouldn't adequately track biometrics.
