The problem with the MapMyRide app (MMR) is that once the data is uploaded to their website, there is no way to export it, other than as a basic route (breadcrumb trail). You lose all the performance data when you export as a route. I much prefer Strava (on my Android 4 phone) or Endomondo (on my older Android 1.6), which let you export GPX files with full time stamps that can also be imported into MMR. Routes exported from MMR can not be imported as workouts into other sites.
The Strava app has worked very well for me. It's as easy to use as any GPS app out there and won't lock your data into a particular website, you can actually download it to your hard drive and own it yourself!
