Fitbit Charge 4 update shows SpO2 data on the band itself, tracks skin temperature

The Fitbit Charge 4 is getting its second major update. While the previous one focused on positioning, this one (first spotted by Storable) is for health data only, as several Fitbit Sense features have been ported over.

First, the Charge 4 now displays proper readings from its SpO2 sensor on the smartband itself. You can use the new Blood Oxygen Watch Face to keep tabs on that. Additionally, the band will now track your skin temperature (something only the premium Sense watch could do).

Even better, Fitbit is making the Health Metrics dashboard free for Charge 4, Versa 2, and Inspire 2 users. Previously, you needed a Fitbit Premium subscription to view detailed biometrics (now including breath rate and heart rate). heart rate variability).

There is a catch, however, free users can only see data from the last week. If you pay for Premium – that would be $10 per month or $80 per year – you can see data for the last month.

The Fitbit app can now also track your glucose levels. You have to enter this manually in the app because Fitbit doesn’t (yet) have a device to automatically track glucose levels. Nevertheless, it creates a useful log, which helps users identify patterns over time.

Meanwhile, Fitbit is expanding the availability of the ECG feature for Sense owners. It can now be used in Canada, New Zealand and US territories. This was already available to users in the Americas and parts of Europe and Asia (this is a matter of regulatory approval).
