M² Editor

M² Editor is a small, focused writing app for people who think in plain text. It is built in SwiftUI for iPhone and iPad, so it launches fast, sips power, and feels like part of iOS. WRITE ON ONE SIDE, SEE THE RESULT ON THE OTHER On iPad, a split view puts the raw Markdown next to the rendered preview. As you type, the preview updates in real time. Drag the divider to give either side more room, or hide a pane entirely when you want to focus. DESIGNED FOR THE IPHONE TOO On iPhone, a segmented control in the navigation bar switches between the Editor and Preview panes. A formatting accessory bar above the keyboard gives you one-tap bold, italic, strikethrough, code, link, heading, list, and blockquote, so you can keep writing without hunting for symbols. A REAL MOBILE TEXT EDITOR The editor pane is built on the native iOS text engine, with all the niceties you’d expect: full undo/redo, smart selection, and a formatting bar that surfaces the most common Markdown shortcuts. Markdown syntax is gently highlighted — headings, bold, italic, code, links, lists, and quotes — without ever getting in the way of the words. OPEN YOUR FILES FROM ANYWHERE M² Editor is a document-based app. Open any .md file from the Files app, from iCloud Drive, or from any file provider. Edits persist to the original file automatically. HEADING-AWARE SCROLL SYNC The editor and preview stay aligned by heading and section. Scroll one pane and the other follows, anchored to the nearest heading so the two views never drift apart. LIGHT AND DARK The editor and preview follow your system appearance or can be overridden independently. Font sizes for the editor and preview are adjustable in Settings. QUIETLY POWERFUL • Split view on iPad, with editor on the left and preview on the right • Segmented Editor/Preview toggle on iPhone • Formatting accessory bar above the keyboard • Heading-aware scroll synchronisation • CommonMark support, including tables, strikethrough, and fenced code blocks • Light and dark preview themes • Adjustable font sizes for editor and preview • Native iOS sandbox — no telemetry, no accounts, no network • Opens .md, .markdown, .mdown, .mkd, .mkdn, and .txt files • Follows relative .md links within the same folder WHO IT’S FOR M² Editor is built for writers, developers, and note-takers who already think in Markdown and want a calm, native app that respects their files and their attention. No sign-ins. No sync services. No AI features bolted on. Just your text and a clean preview. PRIVACY M² Editor does not collect anything. The app is sandboxed, never connects to a server, and stores documents only where you ask it to. Nothing leaves your iPhone or iPad. DEVELOPER Designed and built by Warren Zajac.
