Fitbit Air 30-Day Review: The $99 Subscription-Free Wearable Tested

A hands-on 30-day review of the $99 Fitbit Air, a screenless, subscription-free wellness wearable. The reviewer wore it every day for a month through international airports, a week-long tennis camp in Bali, and intensive training in tropical heat, comparing it head-to-head against WHOOP 5.0. The verdict: the Fitbit Air excels at comfort and sleep tracking and offers roughly 80% of the value at 20% of the cost, but its thin, older sensor hardware lags behind WHOOP during high-intensity exercise, and the Google Health app is still rough around the edges.
