If you're going to ask visitors to answer questions, don't force them to read over things they don't need to know before getting to the meat of it. Just say "Here are some concepts for a _______ app/service, based on these screenshots, would you actively use this tool? If no, what features would you need to use it?"

That said, the response will be from so many different people with different ideas of their ideal solution to this that it shouldn't used to determine the worth. People will try something if it exists, and they'd rather waste their time trying to use it than answering questions about what it is.
