The Fitbit Charge 4 receives its second major update. While the previous one focused on positioning, this one (first spotted by Wareable) relates to health data because several features of Fitbit Sense have been ported.
First, the Charge 4 now displays the appropriate readings from its SpO2 sensor on the smart band itself. You can use the new blood oxygen watch face to keep an eye on this. In addition, the bracelet will now track your skin temperature (which only the premium Sense watch can do).
Better yet, Fitbit makes the Health Metrics dashboard free for Charge 4, Versa 2, and Inspire 2 users. Previously, you needed a Fitbit Premium subscription to view detailed biometric data (now including respiratory rate and breath 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 must enter this manually in the app because Fitbit does not (yet) have a device to automatically track glucose levels. Nonetheless, 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 the United States. This was already available for users in the Americas and parts of Europe and Asia (it’s a matter of regulatory approval).
