The Fitbit Sense is the first wearable built for a post-pandemic world

The Apple Watch will soon be able to detect when you start washing your hands, but if you want to stay on top of mental and physical warning signs in a risk-heightened world, Fitbit wants its newest smartwatch to be the only thing on your wrist. Equipped with stress, heart rhythm, and skin temperature scanners, the Sense might be the most ambitious device Fitbit—or any other smartwatch maker—has ever made.

While it might look a lot like the Versa 3 with a square design and 1.58-inch display, the Sense is loaded with an array of next-gen sensors and algorithms the likes of which you won’t find on any other smartwatch. There’s an ECG app for assessing your heart rhythm for signs of atrial fibrillation, an EDA sensor that detects electrodermal activity, and a skin temperature sensor that logs your skin temperature each night to check for subtle variations. Add a second-gen PurePulse heart-rate sensor and the usual fitness features and you’ve got a device that can understand your body like no other consumer wearable on the market today.
