My first instinctual reaction was I would love content like this, but why does it need to be an app? It's a great idea for a magazine or even a book series or a video series. The multimedia potential of interactive computing devices means you can do all 3 in one, so sure, an app is just a means of delivery, I guess.

Except, it isn't. I was excited that you have a web link, only it's a link that allows you to download the app. I don't want an app. I just want the content.

Is there any plan to ever publish the content you're having generated by any other means? Why not put it directly on the website?
