Most wearable fitness devices do a good job of measuring heart rate, pace and several other metrics. But they typically fail to gauge an extremely important metric for runners: workout intensity.
Stryd was designed to accurately measure running power and efficiency while also offering most of the typical features that other fitness wearables and smartwatches provide. Stryd is a small clip-on device that users can attach to a piece of clothing during a workout. The device tracks data and uses Bluetooth Smart technology to subsequently connect with a wide variety of devices, including sports watches, smartphones (Android and iOS), tablets, and even computers. Notably, the device uses patent-pending sensing technologies developed by Princeton engineers. Each unit costs $149 and will ship in September. Its maker set a Kickstarter goal of reaching $50,000 by April 12.
Stryd holds a lot of promise for fitness enthusiasts, but there are far too many players in the fitness wearables market, including Tracky, to declare Stryd a sure thing.
