Arki (Starts at $109) : If you work in front of a computer all day and find yourself staring at a cellphone during your walk home, you may have a posture problem. Arki by South Korean company, Zikto, has the solution. The wearable band has all the activity tracking functions of a fitness device, but it also has the capability to assess your walking posture and body balance, and send you a notification to straighten up and move right. The device, which will send a vibration to your wrist if it catches you slouching, is expected to start shipping in May 2015.
Arki had a successful Kickstarter campaign in December, raising $164,262.
