Handwriting & PDF Workspace

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Handwrite, annotate PDFs and record the lecture right on the page — all offline on your iPad. 29 pens and brushes, plus flashcards for revision. Free to start. 100 Notes Studio is a private, offline workspace for handwriting, typed notes, PDF markup, page-attached audio recordings and revision. WRITE WITH CHARACTER 29 distinct pens and brushes — fountain pen, calligraphy, fude brush, technical pen, watercolour wash, charcoal, mechanical pencil (2B/4B/6B) and more — each with its own texture and stroke response. Pressure and tilt shape supported strokes, while palm rejection helps prevent stray marks. Pixel, whole-stroke and precision erasers handle corrections. Use the lasso to move, scale, copy or delete strokes, plus a ruler, eight shape tools and a laser pointer for presentations. 100 DISTINCT NOTEBOOK STYLES Each Studio Style has its own cover, paper structure, colour palette, dividers, stamps or stickers, toolbar accent and widget appearance. The collection includes minimal, linen, Japanese grid, academic, engineering, music, meeting, research, planner, travel, wellness, recipe, creative and dark-paper systems.
