From the developer:
Runr offers an easy and simple way to track your runs. After your run ends, you can review details of your run effortlessly on your phone, watch, or computer. While running, Runr will track details, including duration, average pace, distance, minimum and maximum altitude, heart rate, and estimated calories burned. Distance is calculated by using GPS tracking from your phone or watch.
