Sure, but you didn't say how much you would pay for this app, and how would you market it beyond just yourself.

We have a project going that's doing something similar but with food. You'd think that if someone were interested in where their air comes from, they would be even more interested in where the things they choose to put inside their body come from. However, we're finding that the market is either underdeveloped (low awareness) or very small (wealthy people who can eat anything they want). I'd be curious to hear your perspective.
