Okay, I ran Map My Ride for a while, mostly mtn biking and was satisfied. Now on my road bike, I've also been running Strava lately. Can't tell a bunch of difference between the two. I run them as a phone app, no GPS device, and I run them both as I ride. I hate being undecided but can't seem to firmly come down on one or the other. I probably need to run only one, running two uses more battery power. I recently rode and completed a century with both going but the battery was below 10% when finished at 6.5 hours. I'm currently only using the free apps as I can't see any real benefit to the premium subscription.

So I'm sort of leaning toward Strava now. Strava seems a little more "polished" perhaps. I also like the tracking of my own PR's and the segment sections comparisons with numerous PR's and KOM's. Not that I'm competitive against others, but I like to see how I'm doing, where I stand as an older dude against the real riders. I also like trying to best my PR's on certain segments of routes I ride. MMR doesn't track quite those same stats and particularly segments aren't really followed quite like on Strava. It is apparent Strava is much more popular in my area.
On the other hand, IF I decided to run the premium subscription, MMR is $30 vs $60 for Strava. As I said, at this point I see no reason to upgrade beyond the free service.

As it is, I see no reason to continue using both though I do have a fear of one crashing and losing my data if I use only one. In the great scheme of things, I suppose it isn't like that is a life or death situation. Generally speaking, I use things that are useful in life and don't worry about the rest. I hate being so wishy-washy about something so unimportant but for some reason I cannot decide which one to cut loose.

So those of you who use a phone app, which of these two do you run and why?
