C.md — Markdown Reader

Phone-first Markdown reader, not editor. Adjustable line height, foldable headings, saved position, night mode, pinch-zoom pages, and offline PDF & long-image export.

C.md is a Markdown reader for people who read on their phone.

It does not edit. It does not sync. It does not build a second brain.

It simply makes Markdown files comfortable to read on a small screen.

MADE FOR LONG READS ON SMALL SCREENS • Adjustable font size, line height, heading scale and margins • Day and night mode • Chinese and Western fonts selected independently for clean mixed-language text • Optional first-line indent for Chinese paragraphs • Justified or left-aligned, whatever suits the page
