Yup, I came here to note the "its" problem. I won't try the app or look any further, because anybody who can't be bothered to use proper grammar on a publicity stunt sure as hell isn't going to release a quality product.
Regardless - I'd be quietly reprinting and replacing.
In this case, though, I don't feel that it's entirely trivial. Quality is something that happens top to bottom, I believe. Think about Apple -- while I dislike a lot of things they do as far as the walled garden goes -- I feel that they have a quality experience through and through. Every step along the way -- visiting the store, buying a product, even the packaging is well done.
When you have 30 seconds to make an impression on the people that might make or break your future, "that startup that littered a bunch of cars with dead trees and didn't even get someone to proofread" is not the kind of impression I'd want to be making.
