I do plenty of iOS apps freelance. They pay me, I ship the app. Simple.

But, I'm interested in working with some friends to create an app together. Or maybe create an app solely for them, but post it to my store page.

My question, is there an app or site I can use to calculate the revenue of each app individually each month?

iTunes Connect only gives me store rev, not per app. And calculating each month would require downloading all the reports, adding it all up, and converting between currencies.

Thank you.
