One of the most difficult aspects of app development, particularly when launching a new product, is persuading people to check it out. One of two methods can be used to accomplish this:
1) Getting feedback from potential buyers and making changes to the product if they don't seem interested
2) Providing a monetary incentive to registrants. This could be in the form of early access, gift cards, or content sample in today's world. While you wait for this stage of certification, another alternative is to offer your app free with adverts (this is where most apps fail).
Interactive prototyping is one technique to assess and analyze user demands. This method enables teams to decide what they want to do.
