MarkDown Reader - MD Viewer

Tick a box and the file changes. Add a note, and it is all still plain Markdown you can read anywhere.

MarkDown Reader is a free, lightweight viewer for Markdown files. Double-click any .md file and read it beautifully rendered — no editor chrome, no distractions, just your document.

It also turns a checklist into somewhere to work. Tick a task and the change is written straight back to the file, one character, instantly. Add a note to any item and it is saved as an ordinary indented bullet, so every other Markdown tool still reads it. On the Mac, drag a file onto an item to attach it, and click the chip to open it again later.

Nothing is locked in a database. Everything this app writes is plain Markdown you can read in any editor.
