The update is rolling out from today via which Fitbit Charge 4 owners can easily keep a check on their health data through new functions directly from their smartwatch. The update brings the Firmware version 1.100.34 that enables the user to evaluate their blood oxygen saturation (SpO2) while they’re asleep.

Also, the latest software brings the gift feature which lets the user view the device’s activation date i.e; the day when the smartwatch warranty begins. The company clearly mentioned that “the activation date is the day you set up your device.”
