How I Use It
I have used Notability with my students in conjunction with Reflector. Just today my students annotated Article IV of the Constitution and highlighted the different types of responsibilities listed in different colors. If we were 1:1 with iPads or Macs this would be one of the first apps that I would ask for. Notability is a straightforward note taking application that allows you to enter text with a keyboard, write with your finger or stylus, record audio and add images. The killer feature is that you can sync it with Google Drive or Dropbox and your other iOS devices or Mac.
I would give Notablity 4.9 out of 5 stars. My only complaint is that the notes are stored in a proprietary format. You can easily send your notes to someone in the form of a PDF, but otherwise you have to have the app to be able to edit.
