I make about $600/month between ads on the free version and sales for the paid version; not enough to quit my full-time job but a nice monthly supplement.
2. unicornfree.com or @amyhoy on twitter and products coming out of her 30x500 class
I'm hoping to start a SaaS app in the near future, as B2B is far more interesting to me than $1 mobile apps. Having an ARPU above 70 cents and recurring revenue sounds glorious.
That being said, products are the way to go. Last month was actually my best month ever, and I haven't done any work on my apps since January. (some freelance work, some big projects on my property, some traveling)
