About

100 Notes Studio

Features
Read full description

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. MORE THAN A CANVAS Fixed pages or an infinite canvas, with A4, A5, Letter, screen, and custom sizes in portrait or landscape Formatted text with bold, italic, underline, fonts, colors, lists, checklists, tables, and links PDF import and markup with highlights, underlines, strike-through, text notes, handwriting, rotation, cropping, page insertion, extraction, merging, and export Audio recordings attached to the page you choose On-device handwriting and PDF text recognition, with search across titles, body text, handwriting, and attachments Study tools with linked flashcards, cloze cards, and FSRS spaced repetition Stickers, washi tape, and an auto-numbered table of contents Nested folders, tags, pins, favorites, archives, recoverable trash, and restorable page history Ink layers with opacity, visibility, and locking, plus a reference view that keeps a PDF or image beside the page Widgets and quick capture for faster access PRIVATE BY DESIGN No account, ads, third-party tracking or analytics, and no external AI. Editing, search, and study work offline. Notes stay on your device unless you choose to export or back them up. Lock the workspace or an individual notebook with device authentication. FREE CORE, OPTIONAL ONE-TIME UPGRADE The free version includes the core editor, 29 writing tools, PDF markup, page audio attachments, handwriting search, and study tools, with 1 active notebook of up to 5 pages and 2 of the 100 styles. An optional one-time upgrade adds unlimited notebooks and pages, all 100 styles, vector-ink PDF export, restorable page history, and encrypted backup. A focused home for handwriting, documents, and study.
