The Withings scale was ahead of its time. While most of us were still weighing ourselves in the analog world, Withings used Wi-Fi to sync our weight with the cloud. It was one of the first major forays into an exploding trend: Your health as digital data.
Now, Withings is expanding their ecosystem beyond the five-foot radius outside your bathroom. Its Smart Activity Tracker is a tiny, Bluetooth-equipped OLED fob—weighing just eight grams—that’s poised to take on Nike, Jawbone, and FitBit in the ever-more-competitive life-tracking market.
