ZoomNotes Lite is an iPad/iPhone visual note-taking app. It lets you quickly make handwritten notes and sketches on virtual paper, on PDF files, on MS Word, Excel and Powerpoint docs (via GoogleDrive), and over images. Uniquely, it also lets you zoom in and out without arbitrary limits, an invaluable feature for this type of app. It has a free fully functioning pen (although you will be able to try the pens too), and more available as in-app purchases. It has unlimited paper sizes/styles, unlimited colours and line thicknesses, and a large range of ways to share its documents making ZoomNotes the most versatile handwriting/drawing app. ZoomNotes Desktop for Mac now also available.
