All of these work best when connected to an online account of some sorts. Without it, lot of functionality (statistics, data export, map view) tends to be unavailable. There are some local-only apps out there (mostly from the opensource-leaning devs), but they are either buggy, lack important features, or have atrocious interface. What I need is an app combining slick UI and stability of let's say Runkeeper and offline data storage, since I am a luddite and do not care about social networks or 3rd parties having access to my workout data. One can dream, eh? :P
