Early testers love Helium:

It’s so simple to use and has everything I need for running. Other apps are overwhelming with ads and other features.
My absolute favorite thing about this app so far is how easy it is to use and how simple and effective the display is while running. There was no searching for data on a tiny screen while trying to maintain good form. A quick glance and I knew exactly where I was at!
Love the app. Since I run with heart rate all the time, the zones are a fantastic way to keep me where I am supposed to be.
It's everything I've ever wanted in a running app!
