Q:

How can I determine how widespread support of OpenGL ES 3 is?

I am developing new app in OpenGL which should run on iOS and Android devices.
I'd like to use OpenGL ES 3. For iOS that's not a problem, since any iPhone newer than the 5 has GLES 3. 
But I am not sure how wide-spread GLES 3 is in the Android world or if all new devices support it. How can I determine how much support exists for GLES 3 so I can determine if I should use it or fall back to an older version?

A:

The amount of how many devices support different APIs is usually easy to figure out by looking at public hardware stats of popular engines, such as unity and unreal. I recommend using multiple sources of stats to get better view of actual share of different device capabilities.
