What makes the Google Fitbit Air different from a standard smartwatch?

The Fitbit Air has no screen. It tracks steps, active zone minutes, heart rate, and sleep passively, syncing data to the Fitbit app on your phone. The no-display design means a much slimmer profile on the wrist, a lighter build, and significantly longer battery life than a screened smartwatch. It's built for people who want tracking data without the distraction of notifications.

Which band strap should I buy alongside the Fitbit Air Classic?

The Classic comes with one strap; extras let you swap for the context.
