Notes
Exact first worldwide retail day and quantified update commitment measured from launch are unverified. Companion Android/iOS compatibility is not the tracker firmware version. Sold-out or discontinued retail availability alone does not establish ended support. Google currently lists guaranteed security updates until at least 2025-12. This is a minimum period, not an observed final-patch deadline, so it is not stored as a fixed security end. The general commitment is at least two years after last sale through Google Store/Fitbit.com, rather than two years after launch. Firmware verified in maker release notes: 194.91; rollout can be staged. Unknown does not establish zero updates or automatically ended support. AnTuTu is not applicable to fitness trackers.
