iPad Is there an app that can record notes and sync audio?

[madoka]

Just bought an iPad Pro. I'm looking for an app that will record my notes on the screen as I narrate my thoughts. Then I should be able to export it so others can see what I'm writing and hear my thought process as I work out problems. So for example, explaining a complicated math problem.

Does such an app exist?
