I'm building an app that tracks the user's location as they walk on three walking trails (really how far they walk for grant purposes.) I only want to let them track their location if they're within so many feet of the track. (When they hit track or whatever.) I want to compile this info and allow them to see the people who walk the most at their track. I also want to see people who walk the most at each track. Then, I want to be able to view this data on a Bootstrap dashboard. I'm learning as I go. Does anyone have any suggestions to the implementation of this app?
