Apollo for Watch

I have been hoping beyond hope for this app for months so I could leave my phone at home while I run. I was very disappointed when Spotify announced they were releasing a watch app with neither standalone playback nor offline playback. It's pretty astounding that this developer quietly beat Spotify to the punch and that PH was the first I heard of it. This should be getting more buzz because their app really does just work as promised and it came out the same day as the official alternative.
