I'd Like Your Opinion

[Knightoftheapp]

I'm going to have an app developed for use on the iPad. I'm going to have someone develop it for me. Anyone who has ever developed software, knows that it's important to be very accurate and specific when attempting to communicate what you want to the developer so that the app turns out right the first time.

I'm looking for an app that would help me achieve this goal. I have Keynote. Would that be sufficient? Or is there another app that would help me accomplish this task better than Keynote?

Thanks for your help.
