Weight, weight, don’t tell me: This mirror scans your body for better fitness data

They say the scale doesn’t lie, but maybe it’s not telling the whole truth — like how your new daily pushup routine is sculpting your arms. That’s the idea behind Naked Labs’ Naked 3D Fitness Tracker, a mirror that actually scans your whole body to give you better idea of how those hours on the treadmill are working.

The system is composed of two pieces: a mirror and a scale. The Internet-connected mirror plugs into the wall, while the scale wirelessly charges. You stand on the scale, and it slowly rotates to get a scan of you — front, back, and sides. The accompanying iPhone or Android app shows you the 3D images in all their realistic glory. It collects the data and over time can show you that you’re building up your biceps but slacking on your shoulders, for example. The scale will sync with six different devices, so you and your family or roommates can all use it.

The Naked 3D Fitness Tracker uses Intel RealSense sensors for scanning, which use infrared light and takes about 20 seconds. Despite the name, you don’t have to be naked, but the company recommends stripping down to your underwear. It measures your body fat percentage; weight; waist-to-hip ratio; and the circumference of body parts such as biceps, thighs, calves, and hips. It shows muscle gain in blue and fat loss in red.

CEO Farhad Farahbakhshian is an electrical engineer and used to teach spin classes. “Eyes do an amazing job of focusing on problem areas,” he tells TechCrunch. “You get into body dysmorphia if you’re not careful. And it’s hard to stay motivated. This shows people their real progress, or the ‘naked’ truth.”

You can order your mirror and scale now for $499, but they won’t start shipping (and as of now are only shipping in the U.S.) until March 2017.
