It's hard not to be hungry with a 10 bucks app that has a landing page that says nothing about it and competes with Instagram, Camera+, Hipsmatic and such.
After your comment I was expecting a homepage with irrelevant information. Maybe some's blog.
I will not spoil the surprise for others but I will say that I did not expect what I did not see.
Buying your app right now. Go grab yourself a burger.
