I'd say to start out with up to one third of the proceeds available to everyone, then log the time each has contributed to the project. In the end the individual with the most time spent developing the project should recieve their proportionate share.
The main consideration is to keep everyone accountable for their effort/time spent on the project and to have a completion date in mind to keep everyone on track. A well thought out action plan will keep things running smoothly in the long run.
