Vivosmart HR: A smarter band

​Always on: The heart rate data is collected periodically or automatically when the user engages in an activity such as running.

The Vivosmart HR is a powerful, ­feature-packed fitness band with a ­monochrome touchscreen.

Unlike the previous version, it has a ­physical button that lets you change many of the band’s settings. You can modify the alarm, Bluetooth, sync, call volume and ­battery level settings without having to launch the mobile app which is nifty.
