Fitbit Edge vs Air specs comparison
Fitbit Edge is the better all-round choice if you want built-in GPS, a colour display, notifications and on-wrist controls while still keeping roughly week-long battery life. Fitbit Air makes more sense if you specifically want something screenless, lighter and less distracting, but it gives up a lot of day-to-day functionality to get there.
