A new fitness tracker, reportedly called the Fitbit Air, is said to be a screen-less device that competes with Whoop. The device may debut with a subscription service called Google Health, and its price is rumored to be around $100 or £85, although the exact cost and availability are unclear. Some outlets suggest the Fitbit Air will have interchangeable bands and colors, while others mention a possible launch date, but details are not consistent across reports.
