Runmonster
Runmonster has a few things that are nicely done in app. For one there is iPod integration. When you open the app, you can select from any playlists that you have in your iPod app. If you don't have your music sorted into playlists then it won't do you much good. You can't pick from artists or albums so if you want to go that route, then you need to pick the music before you open the app. Once you start your workout, you can change the songs by swipping right to advance forward or left to advance backward. Tap twice on the screen for an update on your progress. I do like the way that runmonster handles your postrun info. It presents it in a neat chart that you can slide your finger accross to see what your min/mile was and your elevation. Overall this is a nice app that misses the mark on one feature that I like about RunKeeper.
Runkeeper
This app is almost identical to runmonster save for a few items. Runkeeper has a few built in training workouts that aide you in well training. This ability to have the program help with training is a huge thing to me. I love to do intervals so you can program an interval where you run hard for x minutes and then slow for x minutes. It also has integration with it's website so you can go and look at your workout later on online with a nice slick site. Where Runkeeper falls short is the fact that there is no iPod integration. It is nice to be able to from within the app add songs from a playlist or control the music. Of course you can set up the phone to do this by double clicking home (if you have that set up in Settings).
Conclusion
Both apps are very nice and tracked my run pretty accurately from what I could tell. They both also can track biking or walking if those happen to be something you would rather track. Runkeeper has a website that you can use to later look at your run and edit it if need be, while Runmonster doesn't. Both have some pretty small things that set them apart, so you just have to look at what matters most to you.
