That's pretty good for such a specialized application, if you ask me. I'm looking to make decent passive income between BlackBerry, Android and iPhone app sales over the next few months, so a few applications with $100 monthly sales would be perfect for what I'm looking for.
You just got yourself another sale...
Oh wow, thanks. It's definitely not as good as the Instapaper iPhone app, but I've been tweaking it over time and it's slowly getting better and better :-).
