In a statement earlier this month, Microsoft insisted that it remains "deeply committed to supporting our customers and exploring the wearables space." (HoloLens is technically a wearable, after all.) At the time, Microsoft also noted that the Band 2 was still actively being sold — but that's no longer the case as of today. The Band's software development kit, which allowed apps to be created for the device, has also been removed. Also in September, the company renamed its smartphone health app to Microsoft Band; that software remains available for existing users.
The Band was a surprise announcement in October 2014, touted as the most advanced fitness tracker on the market. But the device, often criticized for its awkward, uncomfortable design, never really caught on. Microsoft introduced a second-generation model with added features last year, but it also carried forward many of the original's flaws. And now the company has decided to bow out of fitness wearables — at least for the time being — and cede the market to companies like Fitbit, Samsung, Garmin, Misfit, and smartwatch makers including Apple.
