How to read the scores
Each cell is a 1–5 illustrative strength inside that category, not a lab benchmark. A smart ring can beat a band on discreet sleep tracking and lose on glanceable sports UI.
01 / Your priorities
Honest note: Product names and feature sets change quickly. “Fitbit Air” is treated here as a lightweight Google/Fitbit wrist-tracker category for planning. This page is not an official Google spec sheet and does not confirm sensors, GPS, or LTE for any retail unit.

Ecosystem lock-in
Fitbit/Google accounts, export tools and regional app stores differ from Amazfit, Huawei, Garmin and Oura-style stacks. Plan for the phone OS you actually use.
Buying from overseas / daigou?
Region firmware, warranty, charging cables and Google account country can all break support. See the Chinese page for a fuller daigou checklist aimed at CN buyers.
