If you have an idea, but don't know where to start, start by turning your app into a business case. For the same price as a new car, you can build a Minimal Viable Product (MVP) to recruit investors. Even if the MVP has minimal functionality, it will bring a sense of urgency to the situation, encouraging further development. The MVP entices investors, funneling the idea into a tangible form. You build an app, by getting out of your own way and showcasing its potential.
