The Fitbit Sense is the most advanced smartwatch that the company has ever put out. It includes EDA scans, which can detect electrodermal activity. That could indicate your body’s response to stress, and it has a built-in skin temperature sensor which logs yours each night. Allowing you to see how much it varies. There’s also ECG readings that can be done with the Sense. Now this is only available in some countries, and is not intended to be used by those that are under 22 years of age. On top of all of that, the Sense can do all the usual things you expect to see from a Fitbit. That includes tracking your activity, your workouts, and even tracking your sleep. To help you become a more healthy you. Which is always important. The Fitbit Sense can last up to six days on a single charge, and it can give you a full-day charge in just 12 minutes. So if you did forget to charge the night before, that won’t be an issue.
