A few thoughts

* I hear "app" I think "app" as in iOS or Android or Mac app, I have never heard anyone say "app" for "application".

* The whole thing smells of "charge people before you even have a product" to me: you came up with the idea on Wednesday, there is no way you have a system in place to justify asking people for $10.

* You need to establish trust on your front page: why should I do this through your system? A blurry, hand-wavy graph is not enough.
