What WiFi Scales Have to Offer
Bathroom scales haven't changed too much over the years: They all give you a weight readout, via a digital or analog display. Some will also display your body fat percentage, but they don't have to do much else. Enter Internet connectivity. Here's the big draw of a WiFi scale: It tracks data for you. You don't have to keep a chart of your weight loss or enter data each day into an app when it asks for your weight. You don't have to remember the information, because as soon as it weighs you, your WiFi scale uploads data to the cloud.
For example, Withings' WiFiBodyScale uploads your weight information to a free companion service that's accessible via a computer or a dedicated app on iOS and Android. The service keeps track of your statistics long-term, and automatically charts weight loss or gain and body mass index (BMI) based on your regular measurements. The scale can detect up to eight separate users, who can all have their own accounts to keep weight information private.
WiFi connectivity is ultimately about convenience. For example, many people already track their exercise routines with devices like the Fitbit. Fitbit has a Web site and apps devoted to taking exercise data and providing weight goals and calorie counters. The makers of Fitbit also offer aWiFiscale that ties into their existing service. More and more companies are taking this approach to fitness, offering all the gadgets you could possibly need to create a comprehensive tracking system.
Of course, there's a drawback to convenience: It's usually expensive. How much is a WiFi scale going to cost?
