About this app

MarkDev is a Markdown editor made for developers. Write READMEs, docs and notes on your phone or tablet with a live preview that looks like GitHub – then commit them straight to GitHub or GitLab, without cloning anything.

✍️ WRITE FASTER
• A native editor that works with every keyboard, with syntax highlighting for Markdown and code in 35 languages
• Editor, split view and preview – side by side on tablets, with scroll sync
• Smart lists, auto-closing brackets and keyword suggestions inside code blocks
• Undo/redo, find & replace with regular expressions, hardware keyboard shortcuts

👀 SEE IT THE WAY GITHUB SHOWS IT
• GitHub-flavored Markdown: tables, task lists, footnotes, emoji and alerts
• Mermaid diagrams (flowchart, sequence, pie and more) and KaTeX math
• Highlighted code blocks, light and dark themes

📊 TABLES AND DIAGRAMS WITHOUT THE PAIN
• Edit tables in a touch-friendly grid: add, move and align rows and columns
• Paste rows copied from Excel or Google Sheets (CSV/TSV)
• Mermaid Studio: templates, form builders that write the code for you, live preview

🔀 GITHUB & GITLAB (PRO)
• Sign in with GitHub or GitLab.com, or with a personal access token – self-managed GitLab works too
• Open a single file from any repository and branch – nothing is cloned
• Review the diff, then commit & push, or commit to a new branch and open a pull/merge request in one step
• Uncommitted edits are kept as drafts on the device; conflicts are detected

📄 README GENERATOR (PRO)
• A professional README in seconds: shields.io badges, sections, install steps and a table of contents that stays up to date

🔒 YOUR FILES, YOUR PRIVACY
• Open and save .md files anywhere: device storage, cloud drives, project folders, "Open with" and "Share"
• Export HTML, print to PDF, share as text
• No account, no ads, no tracking. Tokens are encrypted with the Android Keystore and sent only to GitHub or your GitLab server.

Free forever: the editor, live preview, tables, Mermaid, math and find & replace.
Pro – one-time purchase after a 7-day free trial, no subscription: GitHub & GitLab sync, pull/merge requests, README generator, badges and table of contents.

Available in English, Tiếng Việt, 简体中文, Español, Português, Français, Deutsch, 日本語, 한국어 and Русский.

What’s new

• New: Markdown cheat sheet (menu ⋮ in the editor, or Settings). Every syntax with an example, its rendered result, and Insert / Copy buttons. Works offline
• Full-screen windows (cheat sheet, Mermaid Studio, table editor, intro) now cover the whole screen on Android 14 and older, and stay above the keyboard
