MD Flow

MD Flow is a native Markdown reader built for Apple devices that lets you browse folders full of Markdown files and preview them instantly. It connects to your existing folders, whether they live in iCloud, Dropbox, or on your local drive, and renders your documents with full support for Mermaid diagrams, KaTeX math notation, Obsidian style callouts, and YAML frontmatter. If you have a vault of notes or a documentation folder and just want to read and search them comfortably on your phone or laptop, this is the tool for that job.

The problem MD Flow solves is the friction between writing Markdown and actually reading it. Most text editors show you raw syntax or force you into a split pane setup. File managers let you navigate folders but give you nothing but code when you open a Markdown file. MD Flow bridges that gap by acting as a dedicated reader that treats your existing folder structure as a browsable library with rendered output on tap.

Under the hood it works as a standard Apple app with no cloud backend. Your files stay on your device or in your chosen sync folder. There is no account, no login, and no server receiving your data. The app simply reads from the folders you point it at and displays what it finds. It tracks your recently opened files across devices through iCloud sync, so if you open something on your Mac you can pick up where you left off on your iPad.

The audience here is anyone with a Markdown heavy workflow who wants a clean reading experience. Developers with documentation repos, researchers with Obsidian vaults, writers who keep notes in plain text, anyone who has grown tired of hunting through folders and squinting at raw syntax. It slots in beside whatever editor you already use rather than trying to replace it.

What sets MD Flow apart is the focus on reading rather than editing. Plenty of apps do both, but very few do reading alone and do it well. The search feature in the Pro version scans across all your connected folders, which is useful when you have thousands of notes and need to locate something by content rather than filename. PDF export gives you a way to share rendered output with people who do not have Markdown tooling.

Pricing is straightforward. The free tier lets you connect two folders and keeps track of five recent files. That is enough to try the app and see if it fits your workflow. The Pro version is a one time purchase at around eight dollars and unlocks unlimited folders, fifty recent files, cross folder search, and PDF export. No subscription, no recurring fees.
