I have to admit that I've never been a huge proponent of the Apple watch. But when GPS was added, my interest was peaked, as I'm a runner. Although I'm still on the fence going back and forth with Garmin Forerunners. I recognize that the AW has potential to be more with a pretty big ecosystem (and it has music storage). But I'm wondering what are the great AW apps? And not just running apps, but what killer app has made the AW indispensable or super productive?
