Fitbit launches new functions for its smartwatches

Fitbit has launched new functions for its Sense and Versa 3 smartwatches with an OS update.
The American company explained that the new Fitbit OS 5.1 operating system supports the Google Assistant voice assistant, and the built-in microphones and speakers can also be used to dictate SMS text messages and receive phone calls directly from the watch.

With the new update, the SpO2 sensor can automatically measure and record the oxygen saturation in the blood at night without the need to activate a special watch face.
