The initial hardware release of Stryd® (now called Stryd Pioneer) was only available for a very limited release. Stryd quickly transitioned to a foot pod hardware version for increased reliability and opportunity for biomechanical data collection. The updated body location enables Stryd® to provide industry-leading training data to our users which cannot be replicated at chest or wrist locations. The foot pod hardware (currently both non-wind and wind hardware versions) is the only format currently compatible with the Stryd® software ecosystem, which includes Stryd Mobile App, Apple Watch app, Stryd® Workout app for Garmin devices, and Powercenter for desktop.
