It was May 28, 2014. Wearables were hot. The tech industry was fixated on digital health and the concept of using on-body sensors to collect data about the “quantified self.” Hype about the as-yet-to-be-announced Apple Watch was getting louder, and lots of people thought that Apple might unveil it at the WWDC developer conference, just a week away. That was the day that Samsung, which already had two smartwatches on the market, chose to hold a splashy Voice of the Body event at the SFJazz Center in San Francisco. With no details about the gist of its announcement available ahead of time, pundits wondered: Would the company announce an advanced health wearable and steal the Apple Watch’s thunder?
