I use the app for both running and walking cardio sessions and it (almost) always works flawlessly. The GPS aspect of the app is awesome and I can always go back and compare my runs, even if I run different routes. Eats up the battery but that is more of an iPhone issue then a Runkeeper problem.

Not a terrible app; does what it is supposed to, monitors the charge on your IPhone or droid. Certainly not a five star app-how about a real 3 and a fake 5?

It seems that this app gets better and better. Used to crash 40% of the time and would take an excessive amount of time to update; now I never crash and updates are seamless. Somebody is paying attention over there!
