Without much fanfare or hype, the first Lenovo fitness tracker makes its way out on the market. The Lenovo Smartband SW-B100 was introduced through a new product page on the company’s site but no official announcement from Lenovo just yet. There isn’t much separating it from its competitors though. It tracks the calories you burned, the steps you’ve taken, heart rate, and sleeping habits. It will even show you notifications about text messages and calls. We will let you know if we get word about price and availability.
