A survey of 10,000 developers by Developer Economics shows that two percent of app developers take in over $100,000 per month.
The data also shows nine percent of developers getting $10,000-$100,000 per month, and 88% of developers on under $10,000 per month.
The study chose a ‘poverty line’ for developers of less than $500 per month - a figure which means their app is unsustainable as a business. A huge 50 percent of iOS developers and 47 percent of Android developers are below that line.
Most games — 57 percent of them — make less than $500/month.
To solve that revenue problem, many game developers release more than one app. In fact, the majority of those making over $100,000/month have published a minimum of 11 games in an effort to give themselves more chances at the app store lottery.
