Pretty good handwriting app for note taking or doodling. Handwriting is very smooth and there is a clipboard tool available for moving various words or diagrams around or to other pages. This app has line, grid, and blank pages available.
RH: There are a lot of free handwriting apps out there and you will use the one that becomes familiar to you. This was a few dollars but because of the smoothing out effect on handwriting is a good deal.
