Run on phone devices for fans of exercise


Health-conscious consumers are snapping up smartphone accessories that record data such as their weight, to help with diet and exercise planning.

In February, for example, SoftBank Mobile Corp. launched a set of bathroom scales with a data interface. Users stand on it and their weight is transferred to their smartphone, which will then estimate body fat. Sales of the product have been double what the company projected, a spokesman said.

A wristband-type device offered by NTT Docomo Inc. acts as a pedometer, measuring steps walked and calories burned. With one of the company’s smartphone apps, users can check their physical condition with data displayed on a graph.

Last September, KDDI Corp., the operator of the au mobile network, launched SHINE, a waterproof motion sensor which can be used at the swimming pool. The company also offers an app that suggests local jogging trails.
