Why SS Markdown

Big files feel like small ones.

Your text lives in a piece tree, the same kind of structure VS Code uses. Typing never shuffles megabytes of text around, and only what's on screen is drawn.

You don't lose work.

A checksummed recovery journal, verified saves, and version history stored as snapshots plus diffs. If another app changes your file, nothing is overwritten without asking.

Calm by design.

Two bars. Copy and Save are always visible, and everything else appears only when it applies.

Edit the way you think.

Switch between Code, Split and Preview, and type straight into the formatted view, tables included, without your hand-written Markdown being reformatted.

Plain files, your files.

Open and save .md files in place from any app, or work across a whole folder. Nothing is locked inside the app.

Everything it does

  • Code / Split / Preview with position kept in sync, plus a pinch zoom that reflows the text.
  • GitHub-flavoured Markdown, footnotes, alerts, front matter, KaTeX maths and Mermaid diagrams (long-press to save as PNG or SVG).
  • Tap-to-edit in Preview and a proper table editor.
  • Navigator: an outline, a quick switcher and drafts, opened by tapping the title.
  • Version history with compare, restore and pinning; recovery after a crash.
  • Folder mode with Save all, and share text in from any app: your recent files appear in Android's share sheet.
  • Copy as Markdown or as formatted text, the whole page or just a selection.
  • Light and dark themes following the system, built-in preview themes, custom themes and Google Fonts.
  • Export to PDF with proper print typography (A4 or Letter).

What it isn't

  • No sync, by design. Use Syncthing, Drive or Dropbox on the files; SS Markdown keeps their changes safe.
  • No tags, backlinks, graph or plugins. It's an editor for files, not a knowledge base.
  • History is per device and goes with an uninstall (you can export it). Your files are never at risk.
