Fitbit Air review $99 screenless tracker takes on Whoop

Fitbit Air costs $99 with no monthly fees, which puts Whoop in an awkward position: Whoop charges a subscription on top of the hardware price, meaning users pay more every year just to keep their data flowing. Apple's fitness tracking also leans on an Apple Watch plus an Apple One bundle to unlock deeper health features. Google is skipping the screen and the monthly bill entirely, which removes two of the main reasons people talk themselves out of buying a fitness tracker.
