About this app

MDVEdit is a Markdown editor with live preview for Android. Write in one pane, watch it render in the other, and take your documents further with tools built for real writing and technical work — all offline.

NEW:
- Live Server — open your document in a desktop browser on the same Wi-Fi and edit it there, with two-way sync. Write on the big screen while the file stays on your phone.
- Mermaid Studio — build flowcharts, sequence and class diagrams from plain text, then pan, zoom, and export as SVG.
- Presentation Mode — turn a Markdown document into a full-screen slide deck.
- Version History — every save is snapshotted, so you can browse and restore earlier drafts.
- Snippets — save reusable blocks and drop them in as you write.
- Writing stats & goals — track word count, reading time, and daily targets.
- Biometric note lock — protect private documents with fingerprint or face unlock.

CORE FEATURES:
- Live preview that updates as you type
- Syntax highlighting for Markdown
- Export to styled HTML and PDF with page numbers
- Multiple editor and preview themes, including dark mode
- Separate fonts for editing and preview
- Works fully offline — no account required, no sync
- Open and save Markdown files from device storage
- Undo / redo, adjustable font size, and focus mode

PERFECT FOR:
- Developers writing README files and technical documentation
- Writers drafting articles, blog posts, and long-form content
- Students taking structured notes and study material
- Anyone who wants to write in Markdown and see exactly how it renders

TECHNICAL DETAILS:
- Supports CommonMark and standard Markdown syntax
- Mermaid diagrams rendered on-device
- PDF and HTML export handled on-device
- Works on Android phones and tablets

FREE AND PRO:
- Writing, live preview, themes, syntax highlighting, and opening and saving Markdown files are free, with no account and no time limit.
- Export is free to try a limited number of times. Free PDF and HTML exports carry a small "Made with Markdown Editor" footer; Word export does not.

Write in Markdown, see it render, add diagrams and slides, and export when you are ready. No account required.

Ratings and reviews

The app is good overall, nice interface. The only issue is the ads. When I minimize it to do something else and opens it up back, an ad every time (although it's skippable at the top) but it pops every time the app is minimized. Everything else is good hence why I give it 3 stars

html output and PDF output should look the same but they do not. the html output properly displayed tables whole the PDF looked unformatted. so now I have to print to HTML before printing to paper for printing that HTML to PDF output

Excellent App. But there should be an option to move between beginning and end of the file. Please let me know, if there is such an option and I missed it

What’s new

Light editor themes with a genuinely white page. "Paper" is free, and "GitHub Light" joins the Pro set. Every light theme is now marked as one in the theme picker, so you can spot them without tapping each in turn.

The existing light themes were hard to read, and now they are not: bold text, headings, links and comments have all been darkened until they meet the standard contrast level. Line numbers in GitHub Dark were nearly invisible and have been fixed too.
