Fitbit has unveiled its Alta HR, a new fitness band that includes a hear rate sensor and OLED display. The device will last for seven days on a single charge, said the company, and also offers sleep tracking data. Sleep tracking data includes how long a user sleeps, along with light, deep, and REM sleep stages.
The data gathered by the band can be viewed on a smartphone via a mobile app.
Fitbit said the Alta HR will sell for £150 in the US and will start shipping in April.
