The Fitbit Versa 3 launched earlier this year alongside Fitbit's flagship tracker, the Sense. That device is packed with features, including heart rate monitoring, sleep tracking, what have you — but it can also do ECG scans, and even purportedly measure your stress levels.
Battery life Three days with the always-on display active, six without; Health tracking Robust. Step and heart rate counts seem very accurate; Design Understated and handsome.
Glitchy software A bug frequently prevents the switching of clock faces. Some info fails to sync for hours at a time; SpO2 tracking No longer tied to a specific clock face, but the stats shown in the Fitbit app are hard to find and not very informative.
