Read full descriptionHide full description
Welcome to ThreadMark, the ultimate local-first Markdown reader that transforms your personal notes, development logs, and reading materials into an immersive, thread-style reading experience! Whether you're organizing a massive "Second Brain" or simply jotting down grocery lists, ThreadMark makes reading long documents on mobile incredibly fast, casual, and stress-free. โ What is ThreadMark? ThreadMark is a unique Markdown viewer and editor that parses your local files into a message board/forum structure. Simply select your local folder (Vault), and the app automatically treats your folders as "Boards", your .md files as "Threads", and paragraphs divided by headings as numbered "Posts". โ Who is this for? - Heavy Markdown users looking for a lightweight, mobile-friendly way to browse their vast knowledge base. - Users of desktop-based PKM (Personal Knowledge Management) tools who want a seamless, local mobile companion. - Anyone who loves the scrollable, bite-sized reading experience of timelines and forum threads. - Privacy advocates who prefer 100% offline, local storage without cloud lock-in. โ Key Features - Innovative Thread-Style UI Documents are automatically split based on headings (e.g., ##) and displayed as numbered posts. Even a 10,000-word document becomes as easy to digest as scrolling through a social media feed. - Rich Markdown Compatibility Fully supports WikiLinks ([[Note Name]]) for bidirectional linking. Tap a dead link to instantly create a new thread. It also beautifully renders inline images, transclusions (embedding other .md files), and callouts (e.g., > [!info]). - Powerful "Quote Anchors" Navigate complex thoughts instantly. Type >>1, >>1-5, or >>1,3 to create interactive anchors. Tapping them opens a quick pop-up preview of the referenced sections without losing your scroll position. - 100% Local & Secure No accounts, no logins, and no forced cloud syncing. All data remains safely on your device's local storage, ensuring your private diaries and sensitive technical notes stay truly private. โ Rich Customization - Dual Viewing Modes Switch seamlessly between the immersive "BBS Mode" (Board/Thread/Post layout) and the traditional "Standard Mode" (Folder/Note layout) depending on your mood. - Beautiful Themes & Typography Choose from a variety of carefully crafted themes, including a classic Retro Beige, pure Dark Mode, Dracula, and Cyberpunk. Includes a precise font scaler to build your perfect reading environment. * Note: ThreadMark is free to use with optional ads. We offer a one-time lifetime purchase to remove ads completely, or you can temporarily hide ads for 6 hours by watching a short video. * Note: This app is a local file viewer/editor. It does not connect to or browse external internet forum services.

Verdict
The clearest difference is in-app purchases: MDDock at none against Thread Mark's 2. MDDock also leads on ads (none vs shown) and update cadence (every 2 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
