I have a Linux/OSX/Windows/IOS/Android client written in Monkey X with a parse-dot-com based back-end developed. I'm in the stage of planning a revenue model for it now but I'm not seeing how you really make money off of it. You can't really charge high-rates for deposit-fees without driving away a lot of users, and selling it through licensing saturates the market.

I actually made the deposit fee dynamic with a cap. It basically factors deposits since the beginning of the month by days to adjust the deposit fee and it changes in real-time..

I figured I need around 400 active users a month just to pay for hosting.. THE QUESTION: Is this why there aren't many people doing this?
