Like the SpO2 sensor, you have to wear the Sense while you’re sleeping for it to get a reading it takes three consecutive nights for the watch to get a baseline reading.

Similar to its blood oxygen and EDA sensor, the Sense’s skin temperature monitor is meant to provide a general sense of your overall health, but is not a primary indicator of any medical condition.

After, it asks you how you’re feeling, and gives you the option of taking a guided meditation session to help you calm down. You can also take an EDA scan, which measures your electrodermal activity, and then factors in your other metrics.

But, the Sense will quantify how stressed you are, not just based on how you feel after doom scrolling on Twitter, but also your heart rate, sleep, and activity levels. I don’t need a watch to tell me I’m stressed. It remains to be seen how useful these metrics are, but Fitbit deserves some credit for trying something new. The EDA and skin temperature sensor are unique to Fitbit, and are meant to give you a better understanding of just how you’re doing. I don’t need a watch to tell me I’m stressed, but the Sense will quantify how stressed you are.Ĭompared to all the best Fitbits, Apple Watch 6 and the Samsung Galaxy Watch 3, the Fitbit Sense is the most ambitious when it comes to new health features.

The screen has three different brightness settings, and you can either adjust the timeout or set it to always-on (which reduces the battery life to about two days). While not as high-resolution as the Apple Watch 6, it was bright, colorful, and crisp, and easy to read even outdoors. I was really impressed with the Sense’s AMOLED display.
