Healbe Smartwatches - Automatic Calorie Intake Tracking

A friend just posted about it online, he got the GoBe2 smartwatch and mentioned that calories seemed be tracking right. Anyone also using their devices? Any Reviews?

I never use mine for counting calories but I’d expect it (a Vivioactive 3) to be way off. The optical HRM always reads a max HR circa 10-20bpm less than my strap/edge :thinking:
