I originally designed the Apple Watch app for my podcast player, Overcast, with a scaled-down version of the iPhone app’s structure.
This seemed like a sensible adaptation of my iOS app to the Apple Watch. In practice, it sucked.
I use Overcast as my main podcast app, but I decided to stay with my Pebble instead of getting an Apple Watch so I make use of the built-in audio remote on the Pebble. The app is basic; essentially consisting of play / pause, rewind, and skip but it works fine.
