According to CNN, Apple’s “tiny” 9% marketshare accounts for 75% of all cell phone profits.
This chart covers all phone sales, not just smartphones, and the whole world, not just the U.S. This teaches a powerful lesson: more marketshare does not mean more money. Not all customers are created equally. Android’s marketshare looks impressive, but when you drill down into the details, you discover that one Apple customer can drive as much revenue as 5 or 10 Android customers.
This is just one more reason to focus on iOS as the primary platform for your application.
