MarkdownPad

A Markdown editor with live preview — write, format, and organize notes fully on-device.

Markdown's design goal was that the source stays readable — a document should look like notes even before anything renders it. That is what makes it durable: a Markdown file written today opens as plain text in twenty years, with no format to migrate and no application required.

Live preview matters most for the parts where the syntax is not self-evident. Nested lists, tables and reference links are all easy to get subtly wrong, and seeing the result as you type is the difference between noticing immediately and discovering it after publishing.
