While weight is far from an absolute indicator of health, it is certainly one that many consumers monitor closely. A modern dark glass and metal affair with a backlit display, the WiFi Body Scale can track the weight of up to eight people. It also calculates an estimated BMI based on a height measurement given during setup and lean body mass by measuring your body's capacitance. As with other scales that estimate body fat and lean body mass, one must weigh oneself in bare feet to obtain this measurement.
As there's no way to enter any data on the scale, it must be set up from the PC using a supplied USB cable or by using the WiScale app for the iPhone/iPod touch. After that, using the scale can be the standard exhilarating or deflating experience
depending on the change you see. Those used to the chatty banter of the balance board in Wii Fit will find the Wifi Body Scale is a silent, non-judgmental servant that provides no positive reinforcement other than a trend line.
The iPhone app and Withings' website provide a colorful user interface that allow you to graph changes over time. The iPhone app takes advantage push notification to remind you of new measurements. While you can export data from the Web site, the service would benefit greatly breaking out of its data silo and playing along with the Web sites of other fitness gadgets to facilitate seeing the impact of activity.
Withings also recently added Twitter support
so you can tweet your weight, although it's questionable whether weight is something that changes often enough to merit frequent updates. The WiFi Body Scale could be a useful motivator and useful tracking tool for someone looking to improve their overall fitness level, but at this point it is more of a novel harbinger of the networked appliance and the era of comprehensive personal health data and self-monitoring. If Withings can build out its service to include things such as fitness tips, integration with nutritionists or personal trainers, sites such as eDiets or weightwatchers.com, motivational messages and the like, then the WiFi Body Scale will have much greater weight in the marketplace.
