Absolutely Perfect
Having tried all the major running apps, I can say with certainty that nothing comes close to the level of iSmoothRun. Its not just how it strives to be compatible with most sensors, or how you can create custom workouts that can be as specific as you want. Its how you can tell that this app is made for running, and nothing else. This single-minded approach results in an app that does eveything that a runner would ever need, without any superfluous features that other apps try to entice you with.
If you are serious about running, get this app.
