What programs are being used to create draw/paint shapes on the screen?

What are developers using to allow the user the ability to paint or draw on the screen? (I do not include HTML5 canvas element in this number - it’s too slow.)

Flash?

I assume this is for phones. Seeing as though it has been posted in “Developing For Mobile Devices”. If I am correct, flash is not an option as it is not supported by iOS. But if that is ok with you, then it is a viable solution. Other than that, I do not think you have many other solutions other than using the canvas or doing it with a native application

Thanks, that seems to be the case.
