Half (50%) of iOS developers and even more (64%) Android developers are operating below the “app poverty line” of $500 per app per month. Maybe it's because there are so many clones and one-off experiments on these stores. For example, how many versions of Piano Tiles / Don't Tap the White Tile are there??? I can't even tell which one is the original at this point. Also, some people will just write an app as a hobby, or to pad their resume. At least for the App Store, if you make $9 per month, you've already paid off your yearly subscription fee of $99, and can safely leave your apps up forever, even if they are below the "app poverty line." I would be interested to see what percentage of developers who are actually trying to make a living from their apps are succeeding or failing.
