finding a real pain point that a customer is willing to preorder with real-money, is much much harder than coming up with a tech solution.

the former is harder because it is totally outside of your control, and the latter is way easier because it is almost entirely within your control.

have you thought of other tech solutions that can address the pain point? e.g. put ipads across the trade floor, with the app already installed, so you don't need to ask users to install anything. Or provide a $3 free coffee deal for every person that uses the app, as a marketing promotion? basically some other out-of-the-box way to solve that pain point that you spent so much effort to find

i would say, don't give up so easily because it sounds like you solved the hardest part (finding the pain point), and you are held up on the easier part (coming up with a technical solution). The tech part can always be adjusted on your end to meet the pain point somehow.
