The Fitbit Charge 4 has received a new update that adds features from the Versa and Sense.
In particular, ‘update 1.100.34’ brings SpO2 blood oxygen saturation tracking to Fitbit’s more affordable wearable. This data will be located in the Charge 4’s new ‘Health Metrics’ dashboard in the Fitbit app, which also includes health metrics like heart rate variability and breathing rate.
Skin temperature tracking, which Fitbit says can help you monitor changes to your body like fevers and ovulation, has also been added to the Charge 4.
The Health Metrics dashboard offers an overview of your seven-day averages for free, but further analyses will require Fitbit Premium.
The update is rolling out widely now to Charge 4 users.
