A post on another thread got me thinking about this. I think it was Dave Cutter, and he said that he switched to a phone app that recorded all of his rides, to track what he was doing. For any app idea, there are nay-sayers, and that's OK because I'm just speculating and asking for opinions.

I know that you can use Strava for this, RideWithGPS, or most any GPS mapping app. I don't use any of them except now and again for two reasons: I don't want to mess with the interface on every ride, and they all seem to be resource hogs particularly but not limited to the battery. But what if it was just a small program lurking in the background and intelligently managed location services, and automatically knew when I was riding and did all of that for me, including optionally sending it to Strava or another site? Or just kept ride and overall summary data locally.

What I want is for the app to do everything without bothering me with it, and not drain my battery or take up much resources while doing it. What do you think, does that functionality already exist? Worth pursuing? Technical issues will sink the idea?
