Meet Naked: a smart mirror with sensors to scan your body to help you see where you are gaining or losing muscle/fat. This device captures a 3D model of your body and lets you view a timelapse of the changes your body has gone through on your smartphone. Simply stand in front of the mirror and scan your body to get started.
Naked helps you track your volumetric body fat %, accurate body measurements, and weight. It has WiFi and Bluetooth. It is expected to ship in 2017.
