Best running app
Ive used this, runkeeper, mapmyrun, and others - I always come back to this one. Simple, quick start, always reliable GPS, and it has never crashed and lost a workout (all the others have). Plus this app writes your runs directly to the other apps, just the same as if you had used those apps to track the run (so they count for challenges and all the data is accessible). Use this app.
