Yes, Apple ‘Watch Series 4’ pioneered ECG/EKG way back in 2018. This is, however, Fitbit’s first foray into this field. That it has got US FDA approval is BIG. Samsung is still struggling to get this approved on their new ‘Watch 3’. That must be galling for them.
The Fitbit ‘Sense’, at $329, is quite the watch. It has built-in GPS & all the latest health tracking features. Most impressive Fitbit ever — & it even has an AMOLED, always-on display with a 6-day battery life. This is quite the watch & it is $100 cheaper than the Samsung ‘Watch 3’. Hopefully I will get one, in October, from ‘Heart Rate Monitors USA‘ (HRM USA) to evaluate. I will keep you posted. OK?
