This is a body composition scale from shop Japan that connects to an app. The price is 11,000 yen. I received it as a gift but I'm not going to use it, so I'm putting it up for sale. It seems you can connect your smartphone to the scale via Bluetooth and measure body fat percentage, muscle mass, body water percentage, BMI, basal metabolic rate, bone mass, and visceral fat. How about it for those who are health-conscious or dieting?
