This wristband looks and feels similar to the Fitbit Flex, and it tracks similar stats, like distance covered, steps taken, calories burned, and hours slept. Like the Fitbit Flex, LarkLife is meant to be worn constantly, and all data is transmitted to an iPhone/iPad app via Bluetooth 4.0 (there’s no LarkLife Android app). The bonus feature that you’ll get with LarkLife: nutrition, productivity, and time management advice from coaches, professional athletes, and business execs. ($150, lark.com)
