Connecting to a wireless scale through your computer is so first-quarter 2012. Now, if you're willing to drop $150 on the new Withings Wireless Scale WS-30, all you need is a Bluetooth-enabled smartphone or tablet to do the trick.
Withings, the French technology company best known for its sleek wireless scales for adults and babies alike, just announced its latest offering at IFA 2012 in Berlin and says the WS-30 will be available in Europe in late September (PDF). Its new (and free) Health Companion app, which helps users track not just weight and BMI (body mass index) but also activities, sleep, and heart rates, is available now.
While Withings' previous-gen wireless scale also measured a user's fat and muscle content and the next-gen one doesn't, it is certainly an upgrade in terms of usability. Whereas before, users had to set up individualized online accounts on a computer that communicated wirelessly with the scale, now one just uses an iPhone/iPad or Android device with Bluetooth and the companion app.
After the initial setup via the app, the scale knows who's stepping on it based on the provided metrics. (I wonder if identical twins of the same weight can fool it.) That info is then immediately viewable in the app.
