It seems as if every major computer company wants to make its own wearable bracelet. The latest to jump into the emerging market is Lenovo, which quietly published a product page for a smart band this weekend. There aren’t many details available, but the device — charmingly named the Smartband SW-B100 — has a small screen and promises to track exercise and sleep. It can also be able to be used to unlock a mobile device and display notifications, and it should work with both Android and iOS. Lenovo hasn’t announced a price or U.S. availability yet, but Android Police spotted that it’s been approved by the FCC.
