I don't trust the cherry picked testimonials on your site.

I don't trust you that your website isn't spam.

I don't trust you with my credit card number.

I don't trust you that your program is well made and follows conventions.

I don't trust you that you won't install a Trojan on my machine.

I don't trust you that you won't put Adware all over.

I don't trust you that your app is bug free and won't ruin the performance on my computer.

But if Apple accepts your app into the app store, I don't have to worry about these things.
