Congratulation, good work! Anyway, the question was about passive income...I suppose you have to do a bit of marketing, user support, thinking about new features, etc...isn't it then just a business?
Perhaps, though it seems like a lot of these responses fall in that category.
I'll say this - I used to work on this app day and night, and now I try and just do the part I enjoy the most, and leave most of it to expert developers and friendly support people. My focus is now on growing the platform, business development, and design work.
