On my Trek, I have the bluetooth DuoTrap S in my frame with magnets on the spoke and crank. I pair it to my iPhone and use iCardio from Fitdigits. Does a good job tracking my mapped route and for display while riding you can have customized stats you want displayed. Been using it for years from the iPhone 5s and up. Also pairs with my old chest HRM via bluetooth (though now I mainly just use my write Fitbit Versa and track calories separate).

My buddy was using MapMyRide. I think does pretty much the same, but I can't recall why I didn't like it as much as iCardio. Maybe way back it drained my battery more or I couldn't pair it.
