Sonar is a method of echolocation used in air or water, as well as an Objective C tvOS app to bring Bandcamp to the AppleTV.

Currently learning to crawl.

Simple, I wanted to listen to my favorite Bandcamp artists on my AppleTV.

Sonar uses the out of the box tvOS UI. You can take a look at screenshots here (with a special shoutout to Deep Jungle).

I've got a bit of a soft spot for Objective C, and in this case it was the quickest path to a proof of concept. That said, Swift would be the right choice to greenfield this as an enterprise product.
