with the 3rd party apps, you do get credit in the exercise ring because it's counting the activity as exercise, but not in the workout app. Endomondo has a glance where it tracks your weekly progress as well as the iPhone app, and Runkeeper has an iPhone app that tracks it. I think the issue is that Apple hasn't opened up the activity/workout apps to real integration with 3rd parties. Hoping that will change soon.
