How much value does the application create for end-users?

If you're targeting consumers, they can be very fickle. As we've seen time and again, they easily shell out $5 for a cup of coffee but complain about $1 mobile applications.

If you're targeting businesses, you got a better shot. Demonstrate how much money you're saving a business, and they'll easily buy. But if your product doesn't create a significant amount of value, it'll be hard to change the status quo.
