Roast my landing page, please!

Hey Szymon!
Since I'm building an App Store application, I can give you some feedback.
First of all, good job :)

For the visual part, the language catches my eyes.
I'm confusing with the word “competition”, I guess in several places I mean “competitor”, “application page” -> “product page” and some other things that I couldn't even find out. English isn't my first language, so I could be wrong, but I suggest you to check your texts with somebody :)

Secondly, the only information that I get from the page is that I can “Discover better keywords”. Other points are too vague to understand, such as “Stay up to date with changes”, “Get ahead of the competition in the rankings”, etc. What does it even mean?
Probably it would be better to use noun forms with short description, like
“Keywords Optimization” – “Discover better keywords”. The bold part should be short and clear.
