Google’s new Fitbit Air , the $99.99 screenless fitness tracker, comes out on May 26th. It’s the company’s first Fitbit release in four years, and you can use it on iOS or Android phones without a paid subscription if all you want to do is track activities, sleep, and basic health metrics (heart rate, breathing rate, etc.). However, for a monthly $9.99 fee, it can tap into Gemini AI-powered features that aim to help you make improvements to your workouts and recovery. All purchases include a textile/polyurethane band that the sensor-filled puck fits into. A perk of preordering ahead of launch is that you’ll get a free second band, or enough store credit to buy one on your own, depending on where you buy from. Amazon is offering the berry, blue, or black color options (but not the greenish fog) that include a silicone band, in white or black, in small or large, for $99.99 (normally $134.99). You can make your choice of band color and size on the Fitbit Air product page .…
