This is simply the best running app of them all. For starters, its simple, beautiful and just works great & accurately, every time. It doesn’t ask me for my email or facebook account like all the others do. RunningTrainer itself is really gorgeous, and very simple to use. I just hit the start button and everything is automatic. It’s not overloaded with silly features no one needs, like the other apps are. The distance and pace tracking is very accurate, and I could very easily change the display to have it show me what I want in a really large font so I could actually see it really well while I was running (with the phone on my armband its not easy if its not large) I like seeing distance and pace first, but they also have calories, time, etc. At the end of the run they have their splits section which lets me see how fast I ran each section of my run, and their map is color coded so I can easily see the speed of each part of my run. I also love their heart rate zone display - really professional way of showing where I strained the most. They also have advanced running programs which look really cool, and I will probably buy their weight-loss plan soon. Last point, the way they let me share my run to facebook is really funny and cool (and they don’t ask for my account, they let ME post). Well done guys. Love it.
