By far the best running app, syncs with runkeeper (and so fitocracy also) – Jog Log - GPS Running, Walking, Cycling, and Workout Tracker Review

Excellent. A wide range of logging and mapping, and the ability to construct interval workouts with different music and targets. Better than the Runkeeper app, (since it lets you create your own workout plans, instead of just buying them) but it syncs with the Runkeeper service.
