I'm building an app for the iPad that can recognize handwriting and I was wandering if there is library/framework for doing that?
Does someone knows how does the other apps do that? do they use OCR or Gesture recognition?

As for me, best of OCR engines is Tesseract; it recognizes text better then even ABBYY.
