Well with watchOS 2 I no longer need to rely on the Workout App when I go for a run! Runtastic Pro is one of the first workout apps that I’ve seen that can receive information from the Apple Watches sensors including heart rate. You can use it for running, biking, walking, and other activities. My experience is with running.

When I start a running activity, I just press the big green button for start and I am off. As I run it is measuring my heart rate, distance, speed, route (as long as I have my iPhone on me), and even filling my activity rings in the Activity app! While running, when I raise my wrist it goes right to Runtastic Pro instead of the clock. In the past if I was using an app other than Workout I had to tell my watch to go to the last app when I raise my wrist. When you are stop your activity, the Apple Watch switches back to its normal mode of displaying the clock when you raise your wrist. While running you can see your heart rate as well as what zone you are in via color bars, total run time, your pace, distance, split times, and music controls.
