A new social platform called Nexus is launching this weekend at the CrossFit central regional tournament in Nashville. The app aims to do for CrossFit athletes what services like Strava and MapMyRun already do for cyclists and runners: provide athletic insights and build a digital community.
The Nexus app is free, but to use it, an athlete first needs to buy a $299 Push Band—Nexus works exclusively with that wearable, made by its sister company. The Band can be worn using a strap or compression sleeve, and has a device that uses both accelerometers and gyroscopes to track both speed, acceleration, and displacement.
