Track Runner

Fantastic app...genius feature is stand out. Rest tracking, commentary, split, share is as good as other apps. I took one star out because UI could have been more colourful and simple like Endomondo

This app is the new gold standard for running apps! I have used this app in a few ultras...a couple in excess of 10 hours for a single run. It is as accurate (if not more so) than my Nike watch or Garmin and in 10 hours used less than 25% battery. I've seen a couple reviews that say "no" or "bad" funny that they come from exactly the same device and have zero feedback...haters are gonna hate I guess

Best running app for Windows Phone. Monitors time, distance, speed, pace, calories, steps, gives voice alerts during run, maps your run with GPS, has visual graphs of speed and elevation, you can log treadmill runs, saves all of your runs, tracks your records...and I'm sure it does plenty more that I am not mentioning. Plus the tile itself looks nice and it uses live tile technology to tell you how many miles you've run that week, which really helps keep you motivated.
