One of the most common app development questions is whether or not the app that is soon going to be designed, devised, and developed even feasible. Well, the only way to get an answer to this question is to test the idea in the field of real prospects. You will have to take your idea, create a working prototype and then make it open in the public to then see if it is something they would be interested in
Until you take your idea to the prospects or at least see how app similar as yours have performed in the market, there is no way to know if yours would succeed.
