This is not a technical problem that creating an app would solve. This is a political problem. The current system gives a lot of power to lobbying. And big companies lobbying the existing governments will not like to change the system to something that gives them less power. How do you change radically the political rules, creating a different distribution of power? Remember that you are at disadvantage: the parties that have advantage in the existing scenario will leverage everything that they have to prevent such rule change (and to prevent the change of even being considered and proposed).
