Totally different from your dad's old needle scale, the Fitbit Aria WiFi Smart Scale uses advanced technology to track weight, lean mass, body fat percentage, and body mass index, allowing you to see all the numbers you need to start living a healthier lifestyle. With room for the storage of up to eight users, this scale recognizes who you are, displays your data, and sends your stats straight to your Fitbit account through your home's WiFi while remaining totally private to you. The sleek polished glass surface looks classy while resisting the condensation from steamy hot showers.
