Long before fitness tracking migrated to smart watches and relegated fitness bands to a niche, Fitbit started out as a nearly screen-free lump that slid into a small plastic holster and clipped to one’s waist. Now, Google, which has been trying to forge a path forward for the venerable fitness device line as it focuses on Wear OS (and its recently announced update to version 7), has taken the sensor back to its roots with the Fitbit Air, a screen-free device so small that it is worn inside a number of fashion-conscious bands. One bit of the Fitbit world you won’t find it in, though, is the Fitbit app, which Google is rreplacing with Google Health.
