You need validation. You don't need to develop the app to have a demo of it. You can put together mockups that look and function the way the finished app is supposed to look and function. You can have someone to put together an animation based on the mockups. If there's a problem it's addressing that people are trying to address, someone's going to want to be notified when the solution is brought into the world.
