It does get disabled to the Quarterback, however I believe the Head Coach can flip between channels to talk to Offensive and/or Defensive coordinators during the play.

It doesn’t have a speedometer function, but I selfhost Owntracks for personal location tracking with my Android smartphone.

It has a back end that an android app sends location too, and a front end that displays those location points over a map. It can display lines between consecutive points, show a heatmap of the location points, filter location history within windows of time, and more.
