Fitbit Alta HR Activity Tracker

A few of Fitbit’s fitness monitors trackers already come with heart rate sensors packed inside. The Fitbit Alta HR is another to add to the list, and the brand’s thinnest — and indisputably best looking — that monitors heart rate to date. The OLED display-equipped device’s shrunken PurePulse heart rate sensor tracks your pulse all day long while barely affecting battery, lasting for a solid seven days per charge. Like the non-HR Alta it of course also counts steps, distance covered, calories burned, stationary time, and identifies activities (namely, sports) automatically, classifying them in the app’s exercise section. It’s also compatible with a wide range of bands in various materials (leather, metal, rubber, etc) and syncs stats wirelessly to any relevant iOS or Android device.
