Apple is not the only company building smart wearables. The Microsoft Band has been around for a while. The new version has a curved AMOLED display with Gorilla Glass 3. It has 11 sensors to track your heart rate, exercise, calories burned, and sleep quality. You get a barometer, UV monitor, GPS, and other tools to keep an eye on your health.
Microsoft Band offers Cortana integration, so you can preview messages on your wrist and respond with your voice. The device is compatible with iOS, Android, and Windows devices. It will be available for $249.99 at this time.
