Sounds like he's contributing the minimal funding (how minimal?), and you're building the entire app.

Without knowing more, I would say that you two need to go into this at 50/50 equity if you are going to both be bringing that much value to the deal. If not, you should allocate equity accordingly.

Just going off what you've written, I'd say he should be the one taking a 20% profit share and 10% sale share. It may be his big idea, but the world is full of big ideas, and short on people who make them happen.
