The Withings WiFi scale makes tracking your weight a little easier (and more fun). Instead of writing down your weight and body fat, the scale sends this information to a personal, online account, which keeps track of your stats.

Like many modern scales today, the WiFi scale determines body fat by sending a small electrical current through your feet and measuring the resistance of the current, said Jean-François Kitten, spokesperson at Withings. (This works because body fat doesn’t conduct electricity, unlike the muscles and water in your body.)

You can also soup-up the WiFi scale.

“The Withings scale is like an iPhone,” Kitten said. Just as apps make the iPhone more than a phone , online services make the WiFi scale more than a scale.

For instance, a person’s weight stats can be sent via WiFi to a personal Google Health account, which stores health records that can be shared with doctors and other healthcare providers. Or, if you want, “you can tweet your weight to your followers and maybe receive some encouragement from [them],” Kitten said.

There's also a free iPhone app for the scale.
