Just a Markdown Viewer App Store
Available on the Mac App Store
Free · No ads · No in-app purchases · Requires macOS 14 or later
macOS 1.0 is live on the Mac App Store as of August 4, 2026. The iPhone & iPad build is still pending Apple review, so that App Store link will land here once it clears.
Just a Markdown Viewer does exactly one thing: it shows you markdown files, beautifully. No editor. No preview pane bolted onto a text editor. No sync service, no account, no subscription. Open a .md file and read it in a clean, centered, monochrome reading column — the way a document should look.
Minimalism here is a deliberate product constraint, not a missing feature. The app is view-only on purpose: it renders headings, lists, tables, code blocks, quotes, links, and task lists, and gets out of your way. On Mac, files open as tabs Chrome-style — drag a tab out into its own window, or merge them back into a group. On iPhone and iPad, documents open straight from the Files app.
What It Does
- View only — renders markdown cleanly, with no editing by design
- Formatted ⇄ raw source — one toggle between the rendered view and the raw text (⇧⌘R)
- Native text selection everywhere — select, select all, and copy
- Light, dark, or system appearance (⇧⌘D to toggle)
- Chrome-style tabs for multiple files on Mac — drag out to split, merge to regroup
- Opens
.md,.markdown,.mdown, and.mkd, plus plain text - Universal app — one purchase covers macOS, iOS, and iPadOS
What It Doesn't Do
- No editing — that's the entire point
- No data collection — no analytics, no tracking, no accounts, ever
- No network access — files are read from disk and never leave your device
- No ads, no in-app purchases, no subscriptions

FAQ

- Which file types does it open?
.md,.markdown,.mdown,.mkd, and plain text. - How do I view the raw source? Toggle between formatted and raw with ⇧⌘R.
- Is it free? Yes. Free, with no ads and no in-app purchases.
- Where do I get it? On Mac, use the Mac App Store link above. The iPhone & iPad version is still pending review, and that App Store link will appear here once Apple approves it.
