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.
