About this app
Justdown is a markdown note-taking app built for Japanese language learners. - Aozora Bunko / Pixiv notation: 漢字《かんじ》 renders as ruby text over the kanji - Use the vertical bar to mark the base explicitly - Standard HTML ruby tags are also supported for pasted content - Quotation marks 「」『』 are never touched, so you can write natural Japanese freely MARKDOWN EDITOR - Live preview with GitHub-flavored markdown: headings, lists, tables, quotes - Syntax-highlighted code blocks (light and dark themes) - Keyboard toolbar for one-tap input of furigana brackets, headings, bold, and code blocks, so you never fight the Japanese keyboard for special characters BUILT FOR STUDYING - Table of contents panel: jump to any heading instantly - In-note search with match count, working in both editor and preview - Full-text search across all notes - Auto-save as you type PRIVATE BY DESIGN - All notes are stored locally on your device - No account, no ads, no analytics, no network access
