Noteful is a digital note-taking and annotation app optimized for handwriting on iOS devices that blends fluid pen input with powerful document tools. You can write naturally using Apple Pencil or touch input; its custom ink engine records strokes as scalable vector ink, and you can switch between three brushes (ballpoint, fountain, highlighter), sizes, and colors. Beyond handwriting, Noteful supports importing PDFs and Office documents, annotating with typed text, images, and shapes, and layering multiple paper templates within a single notebook. Notes can be organized flexibly via hashtag tagging (including nested tags), rather than rigid folder structures, and you can browse content by tags or pin important pages. It offers a layer system so you can annotate without altering base content, hiding or reordering layers as needed. Editing tools include a precise eraser, lasso selection for moving or resizing content, unlimited undo/redo, and split-view multitasking.

Combine handwriting, photos and typing in a single note to bring your projects to life. Use a wide range of note-taking and sketching tools to capture every detail. You can even add and annotate PDFs in Notability. It’s the perfect place to create and organize work, school, and life's information! Experiment with different tools to create beautiful, hand-crafted notes and sketches. Continue to scale, rotate, and recolor your ideas and sketches until your notes are just how you want them. Once you're done, organize your notes with ease so you always know where to find what matters most. Zoom in on the specifics, or explore the big picture by combining sketches, outlines, and type. Now you are ready to share your notes with colleagues or study partners through Google Drive, AirDrop, Email and Dropbox.
