Most landing pages on the web look the same too. The best signup flows I've seen or created don't need to continually re-enforce why the user is signing up, they just need to lead the user down a logical path towards fulfilling the original value proposition, the reason they typed their password into the App Store and took the time to download your app in the first place.

If the user is bouncing because they think "this is going to take a while" then you either don't have a strong enough value proposition or you're making the user think too hard. Most things can be reduced to simple, one-decision steps, and when you do that things will generally convert better for you.
