Not only do you already offer a free version, but the regular app is $0.99 and still gets ripped off. That's just sad.

Its disgusting. People seem to think "Oh I've paid £500 for the iPhone, I should get all apps for free!" and sometimes don't realise that not all the apps are created by Apple. I'm a student programmer and a lot of my fellow programming students have JB'd phones just to download 59p (now 69p!) apps for free, yet they spend 4-6 times as much on a beer. It really infuriates me because developers like the OP put in a lot of work into their apps for a price that is simply a steal and yet people won't pay for it. Jeez.
