I know the advantages and disadvantages like battery life and things like that. But I have a pretty nifty holder for my smartphone on my bike stem and for the time being I would like to use my smartphone to do more than just map my ride. I mean I would like to be able to actually input a map on to it a particular course that I wanted to ride. I see on Google Maps I can create my own course. My question is what would be the best app to use on my phone to import a created map to? I have my tracks recently installed but I've never used it. And I always use Strava when I go riding. And of course I have Google Maps that came installed on my phone. I don't see anywhere in Strava to import a route. So my question is between my tracks and Google Maps would 1 be better for this purpose as far as battery drain? And is there any other apps out there that can do it all without having to use Google maps to do the creating?
