To successfully create a new mobile application, it is important to consider it as a product in its own right, and to think of its development within a life cycle. For apps aimed at a very large target audience, it is strongly recommended to test with an increasingly large panel of users as the product creation phases progress. It is thus recommended to proceed to a beta-testing phase: with a panel of users, to integrate the feedback and possible corrections before putting it online on the stores.
