Google just made its most serious moves yet into the fitness tracker market. The maker of the Pixel Watch has officially unveiled the Fitbit Air, a screenless health band priced at $99.99. Unlike Whoop, which locks all the fitness data behind a paywall, Fitbit Air’s core health-tracking features will remain free.  Currently available for pre-orders, the device will start shipping across 21 countries starting May 26, 2026. You can get the tracker in four Pixel-like colors, including Obsidian, Lavender, Fog, and Berry, and choose from three different strap styles: Performance Loop, Active Band, and Elevated Modern Band.  Google What does the Fitbit Air actually track?…
