“Simply hold your fingers on the corners of the stainless steel ring around the watch while being still for 30 seconds to receive a reading that can be downloaded to share with your doctor,” Fitbit said in a statement. This is the first device from Fitbit that includes ECG functions. Sense-wearers can measure their heart’s rhythm for signs of atrial fibrillation using the ECG app. “The combined on-device and in-app experience with Fitbit Sense gives you insights into your body’s response to stress with tools to help you manage both your physical and mental stress,” Fitbit said in a statement. To track the EDA, users place their palm over the Sense watch face to detect changes in electrical charges in the skin’s sweat level. The EDA sensor measures the body’s response to stressors to help users manage their stress, according to Fitbit. It costs $329 and includes a free six-month trial of Fitbit Premium.

The Fitbit Sense marks the company’s first “advanced health” smartwatch, including an electrodermal activity (EDA) sensor, an electrocardiogram app, a heart rate tracker and an on-wrist skin temperature sensor with more than six days of battery life. Fitbit announced today three new wearables – the Fitbit Sense, Fitbit Versa 3 and Fitbit Inspire 2 – to its product pipeline.
