The new Fitbit Sense is not a fitness tracker, nor is it a regular smartwatch. No, the Fitbit Sense is a ‘health smartwatch’ that comes equipped with a myriad of sensors to track and measure your bodily and functions and emotional state, all at once. The main appeal of the here, apart from the eye-catching design, is the ECG and AFib features, all measured on the wrist and fed into the Fitbit App.
And as of the 14 September 2020, Fitbit has received 510(k) clearance from the FDA (in the US), as well as the CE marking in the European Union, for its electrocardiogram (ECG) app to assess heart rhythm for atrial fibrillation (AFib), meaning it’s not just Fitbit saying the Sense can do all these accurately.
Having said that, the ECG function is not active at launch.
