With tools to monitor heart health, stress management and even skin temperature, this is a bit like having a medical assistant around your wrist at all times (it’s no substitute for your regular doctor). This is the second generation of Fitbit’s health-focused smartwatch, and the updated interface and the return of the physical navigation button make this wearable particularly appealing — especially at this price. Besides keeping a close eye on atrial fibrillation (heart rate irregularities), this Fitbit includes a cEDA sensor that detects electrodermal activity, which often correlates to your body’s response to stress. You can also see your nightly blood oxygen levels at a glance.Â
It still has all the great features the first-gen Sense offered, like built-in GPS for hikes, biking and driving. The watch also has Amazon Alexa built-in for news updates, bedtime reminders and alarms, and it can control smart home devices too. The smartwatch comes with a variety of clock face options. One battery charge lasts six full days, and a full day’s charge takes only 12 minutes.
