A feature that is incredibly helpful in note taking apps is the zoom to write feature. This allows you to enter your notes by hand in a larger form and the app will place the notes more precisely within the note.
The developer describes the app as follows:
•• Full-featured Handwriting ••
Pour your thoughts, ideas, and notes onto a personal canvas. Write wherever you desire with amazingly smooth digital ink. Use zoom-view to quickly record the smallest of details. Use the palm rest to protect the screen while writing. Choose a paper to suit your style while using a variety of pen colors and widths to create beautiful notes.
•• PDF Annotation ••
Import a class note, syllabus, lecture, presentation or book chapter, in PDF format. These documents provide great context for note taking. All of the tools are available for annotation, including pens and highlighters, writing blocks, images, type, and more.
•• Advanced Word Processing ••
When speed and accuracy are essential to your notes, the advanced word processing features supply the perfect tools to assist you. A fully customizable tool bar places your favorite tools a touch away: font presets, bold, underline, italic, and cursor controls help you compose notes quickly. Create outlines easily using bullets or numbers. These are just a few of the tools that integrate seamlessly to support your note-taking style.
•• Linked Audio Recording ••
Audio recordings automatically link to your notes. Confidently take notes, with the knowledge that linked recordings help with review. During playback, simply tap a word to hear what was said at that moment. Our unique audio amplification features create brilliant recordings in any setting.

Enhance your notes with pictures from your photo library or iPad 2 camera, web clips, figures and writing blocks. You can move and resize these, so they take the proper place in your notes.
