Looks like it's part of their Quik app which is free.
Would love to see this work with my GoPro Session camera but looks like it's for the Hero5 Black.
Davi Millsaps IG has a video of it in use
Nice!
I've been getting performance data (HR, Speed, Avg Speed, Laps, etc) from a Garmin 310xt.
Maybe someone will make a widget/app to incorporate with my GoPro Session.
