Crowd funded in 2017, the Naked 3-D Fitness Tracker is now shipping for $1,395, a significant hike from the $499 the company listed it for originally. It gives the customer the ability to do a body scan for fat percentage, weight, lean mass, and fat mass. It does this algorithmically by comparing your images with a database of body shapes and DEXA scan data (dual energy x-ray absorptiometry, and it measures bone density as well as body fat estimates). It can be yours for a cool $1,395.
