SoloMD vs MathNote

SoloMD is a calm, fast Markdown editor for iPhone and iPad. Open the app and you are writing — no account, no sign-up, no subscription. Your notes are plain .md and .txt files. Keep them in SoloMD's folder in the Files app, or open a folder you already use, and edit the files right where they are. Any editor on any device can read them, today and in ten years. WRITING FIRST - Live editing: Markdown marks step aside once the cursor leaves the line, so you see the document, not the syntax. - Real typography: big headings, true bold, monospaced code, comfortable line length. - Focus mode dims everything but the paragraph you are in; typewriter mode keeps your line at eye level. - A formatting bubble appears over selected text; a keyboard bar puts headings, lists, links and code one tap away. - Find and replace with match case, whole word and regular expressions. - Light and dark themes that follow the system. ON IPHONE - A notes home screen, search and a new-note button within thumb's reach. - Full-screen editor with a simple navigation bar. ON IPAD - Sidebar with your folders and notes, tabs, and an outline of the current document. - Split view and Slide Over friendly; works with hardware keyboards and ⌘ shortcuts. MARKDOWN THAT GOES FURTHER - KaTeX math, inline and display. - Mermaid flowcharts, sequence diagrams and Gantt charts. - Tables, task lists with tappable checkboxes, footnotes, front matter, highlights. - Syntax highlighting for 13+ languages. - Tap an image or diagram to view it full screen with pinch-zoom. - Fold headings to see the shape of a long document. FOR CHINESE WRITERS - Simplified ↔ Traditional conversion, pinyin, and CJK-aware word counts. - Chinese proofreading for half-width punctuation and common slips. - Opens UTF-8, UTF-16, GBK and Big5 files correctly. EXPORT AND SHARE - PDF with math and diagrams rendered. - Word (.docx) with tables kept. - HTML, or copy as HTML, plain text or Markdown. PRIVATE BY DESIGN SoloMD collects no data.
