100 Notes Studio: Pen & Paper

Optimized for iPhone Duo. Built with the latest SDK, the app fills the entire inner display and automatically adjusts its layout whether the device is folded or open.

Handwrite notes that feel like pen on paper: 29 pens and brushes, from fountain pen and pencil to fude brush and watercolor, and your handwriting is searchable later.
Mark up lecture PDFs, record audio right on the page you are writing, then review with flashcards and spaced repetition.
Choose from 100 notebook styles. Core editing works offline.

WRITE WITH CHARACTER
29 distinct pens and brushes — fountain pen, calligraphy, fude brush, technical pen, watercolor 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, color 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. Browse and preview all 100 styles before choosing one.
