Is the revenue plan based on a monthly subscription model? If not, then I don't know why you'd want to think in terms of "X USD per month"[1].

That being said, kudos, the app looks really fun. It seems to me that you should charge the one-time d/l fee ($0.99 USD)

It's not a subscription no. But if our retention mechanism works, and the app is good enough, people who really like it will be able to spend money in it regularly.

Our quote from the blog is more of a fact than a reference to our business model. Cause if we don't make 15K in per month in average by mid-February, we're out of business.

I understand what you're saying, but it's not intuitive (for me, at least) to map variable in-app purchases to a fixed monthly expense model.
