I agree on the point of desktop. I do listen on both desktop and phone. I wanted to flush out the idea on desktop with a mobile friendly version. I have the ability to generate an app using NativeScript. Which is hopefully coming soon.

The inspiration came from while listening to podcasts and wanting to take notes about interesting content within each episode. Podcastmarks allows me to bookmark specific points within an episode and add a note so I can refer back to it at a later time.

I really appreciate the feedback!
