One of the primary challenges in app development, especially when introducing a new product, is convincing customers to try it out. This can be done in one of two ways:
1) Soliciting feedback from prospective customers and adapting the product if they don’t seem engaged
2) Using an incentive for registrants. Nowadays this may come in the form of early access, gift cards, or content sampling. Another option is to make your app free with ads while you are waiting on this validation stage (this is where most apps fail).
One way to validate and evaluate user needs is through interactive prototyping. This process allows teams to design and iterate quickly around what matters most without investing too much time into app development. Interactive prototypes provide.
