Markdown MD Editor & Reader

📝 Open the markdown files you already own

Markdown MD Editor is a markdown editor, viewer and reader for the .md files already sitting on your phone. Open a markdown file, see it rendered instead of as raw syntax, edit it, and save it straight back to the same file in the same place. No account. No upload. No new home for your notes.

📂 File-first, not app-first

Most note apps want you to paste your writing into their database. If you already keep notes, READMEs, drafts or documentation as markdown files, that is backwards. This markdown notes app opens the file where it lives, through your device's standard file picker - local storage, or a folder already synced to your device - and writes your edits back to that exact path. No copy is made. No duplicate appears in a folder you did not choose.

👁 A markdown viewer that actually renders

Rendered markdown means headings at the right size, tables laid out as tables, links you can tap, and bold and italic where you typed them. Switch to edit mode to change the text, switch back to preview to read it. It is a markdown reader and a markdown editor in the same place, which is all most people wanted from a plain text editor on mobile.

🛡 Save in place, without losing work

Editing the same file in two places is normally how notes get lost. Before saving, the app checks the file on disk. If it changed since you opened it, you are told and asked what to do, instead of the newer version being silently overwritten. If a file becomes unreachable while you are working, you are offered somewhere else to save rather than losing the edit.

📋 What you get

- Rendered markdown - headings, tables, links, lists, bold, italic

- Open .md and .markdown files with the standard file picker

- Save in place to the original file path, not a copy

- Works with local files and already-synced folders

- Warning when a file changed outside the app

- Export a document to PDF and HTML

- Visual themes including a minimal monospace Mono style

- No account, no login, no forced sign-up

- Offline - opening, reading, editing and saving all happen on your device

👤 Who it suits

Developers reading a README on the move. Writers who draft in markdown and want the draft legible on a phone. Students keeping course notes as plain text. Product managers writing user stories and specs. Anyone with a folder full of .md files and nothing decent to read them with on mobile.

💡 Getting the most from it

Keep your markdown files in a folder that already syncs to your device, and this app will read and write them there without adding a sync layer of its own. Use preview for reading and edit mode only when changing something. Export to PDF when handing a document to someone who does not read markdown. Try the Mono theme for a monospace, distraction-free page.

🚫 What it deliberately does not do

Syncing depends on the cloud storage you chose - the app reads and writes what is already on your device or in a folder you already sync, and has no cloud service of its own. And there is no subscription. Saying so up front is easier than disappointing you later.

💳 Free, with one optional purchase

Opening, rendering, editing and saving markdown files are free and need no account. One single purchase unlocks PDF and HTML export plus premium themes including Mono. One payment, not a subscription.
