Then at the end, when I tried to buy it, it was not available. I had assumed that the app may have been censored or pulled.
Well, good news. The app isn't in the store yet. However, the developer, Tiverias, pointed it out on their Twitter feed that they're still working on it. Apparently, it was not quite ready yet.
But hopefully, they'll get it out to us soon enough. If you like to be kept up to date, you can follow their feed here at Twitter.
