OpenMark 1.2: iOS App, Writing Modes, and Themes
OpenMark 1.2 brings an iPhone and iPad companion app, Focus/Typewriter/Zen writing modes, 4 editor themes, image paste, and MDX support. One $9.99 purchase — Mac, iPhone, and iPad.
OpenMark 1.2 is out. It's a significant release: a native iOS app for iPhone and iPad, three new distraction-free writing modes on Mac, four editor themes, image paste and drag-and-drop, and MDX file support.
The iOS app is included in your one $9.99 purchase. Universal Purchase means if you own OpenMark on Mac, you get iOS for free. If you own it on iOS, you get Mac for free. One purchase. One price. All three devices.
The iOS Companion App
The biggest feature is iOS. OpenMark is now on iPhone and iPad.
The iOS app does what you'd expect from a markdown reader: it opens .md files from iCloud Drive or any document provider, renders them beautifully, and lets you read them offline. Your writing, always with you.
Rendering works the same way as Mac: Mermaid diagrams render inline, LaTeX math typesets properly, code blocks get syntax highlighting. Tables, lists, blockquotes all look right. You get the full markdown experience in your pocket.
Dark and light mode both work. The app respects your system settings and adapts automatically. Or you can override it in the settings.
Adjustable font size and line spacing. If you prefer larger text or more breathing room between lines, it's there. You can customize the reading experience without leaving the app.
Four editor themes (same as Mac): Default, Nord, Solarized Dark, and One Dark. Apply them to both the document view and markdown view.
Interactive elements work. Checkboxes in your markdown are clickable and update as you check them off. Links are tappable. The app isn't just showing you a picture of your markdown — it's interactive.
iPad-specific features unlock the larger screen. Split View with a table of contents sidebar on one side and your document on the other. Drag and drop between apps. Apple Pencil support for handwriting. The full iPad experience.
Siri Shortcuts. Automate reading and exporting your markdown files. Trigger actions based on file names, dates, or content.
Quick Note and Handoff. Start reading on your Mac, hand off to your iPad, continue where you left off. Quick Note integration means your markdown files surface in the system quickly.
Home Screen Quick Actions on iPhone. Long-press the OpenMark icon and jump directly to frequently-opened files.
Find in page. Search through your document without jumping around. Find all instances of a word or phrase.
Spotlight indexing. Your markdown files appear in Spotlight search on iOS. Search by name, tags, content.
Print and export. Export to PDF or print your markdown files directly from the app. Rendered diagrams and math stay intact in the PDF.
Works offline. No internet required. Open a file, read it, edit it, all without WiFi.
Writing Modes on Mac
One of the most common requests after launching OpenMark was: "I need fewer distractions when I'm writing."
Version 1.2 adds three distraction-free writing modes for macOS:
Focus Mode (⌘⇧F). Dims everything except the paragraph you're currently editing. Your cursor sits in the center of the screen, and all other text fades to 40% opacity. This forces your attention on the sentence in front of you. No skimming. No jumping ahead.
Typewriter Mode (⌘⇧T). Keeps your cursor vertically centered on the screen at all times. As you type, the document scrolls to keep your line of input in the middle of the window. It feels like old-school typewriter behavior — the paper rolls under the roller, and you always write at the same spot. Oddly satisfying.
Zen Mode (⌘⇧Z). Hides the toolbar, the document list, the menu bar, everything except your text on a dark background. Full-screen focus with no UI chrome. Just you and your words.
All three modes work in Markdown view (the raw editing view). You can combine any mode with any editor theme.
We also added a Word Wrap toggle in the View menu for people who prefer fixed-width lines in the editor.
Four Editor Themes
Previously, OpenMark shipped with one editor theme: a clean default with dark background. Not anymore.
Default. The original. Light gray text on a dark background, clean and minimal. Good contrast, easy on the eyes.
Nord. The popular Nord color scheme — cool blues and greens, inspired by Arctic ice and nights. If you use Nord in VS Code or your terminal, you'll recognize it.
Solarized Dark. The other classic. Warm tones, high contrast, designed for readability. Solarized has been a favorite for over a decade.
One Dark. From the One Dark syntax theme for Atom. Purple accents, dark background, modern and slightly warmer than Nord.
All four themes work in both Document view (the rendered, read-only view) and Markdown view (the editing view). Switch themes in Settings.
Image Paste and Drag-and-Drop
You can now paste images directly into your markdown files.
Press ⌘V to paste an image from your clipboard. Or drag an image from Finder into the editor. OpenMark saves the image to the same directory as your markdown file and inserts the proper markdown syntax: .
If you're editing a file in iCloud Drive or another cloud folder, the image gets synced along with your document. If you're working on a local file, the image is saved locally next to it.
It's fast, it's seamless, and it means you don't have to manually organize images anymore.
Other Improvements
Move Lines (⌥↑ / ⌥↓). Select a line (or multiple lines) and press these shortcuts to move them up or down in the document. Useful for reorganizing thoughts without cut-and-paste.
MDX file support. OpenMark now opens .mdx files (MDX is markdown with embedded JSX, often used in documentation and blogging platforms). If you work with Claude.md files or other MDX content, OpenMark can read them.
Tab width customization. Choose 2, 4, or 8 spaces for your indentation. Set it once in Settings and it applies everywhere.
Bug fixes: Undo (⌘Z) now works correctly across all scenarios. Fixed image paste on iOS. Fixed an XSS vulnerability in the iOS rendering layer. Fixed a memory leak that affected iOS documents with very long content. Added proper share sheet support on iOS.

OpenMark 1.2 is out now on the Mac App Store and iOS App Store.
