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. ■ 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". ■ 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. ■ 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. ■ 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.

Igneous is a notes app you drive with one thumb. On iPhone there's no toolbar at the top of the screen: everything lives in one dock at the bottom, and it moves the way Safari's tab bar does. Your notes are plain Markdown files in a folder you choose — on your device, in iCloud Drive, or anywhere Files can reach — so they open in any other app, today and in twenty years. No account, no database, no analytics. GET ANYWHERE WITHOUT REACHING • Tap the pill in the dock to search every note, like tapping Safari's address bar. • Swipe it sideways to move between open notes, and keep going past the last one for a new note. • Swipe up on it and your open notes spread out as cards. • Swipe in from the left edge for your notebook, and from the right for the Inspector. • Pull down on a note to find a word in it. Hold any button for more. • While you read, the dock folds into a slim pill out of the way. Liquid Glass on iOS 26; solid with Reduce Transparency. • On iPad: a floating notebook pane, a real tab bar, and as many windows as Stage Manager will hold. CAPTURE THE MOMENT • Press the Action Button, a Lock Screen widget or a Control Center tile and you're typing in a new note — even from a closed app. • Record a voice note from the Action Button, Siri, the app icon or the note you're in. Igneous transcribes it on your device while you talk, shows the words on the Lock Screen, and saves the audio and transcript into today's note or a note of its own. • Copy a voice note — recording and transcript together — and paste it into Messages, Mail or another note. WRITE IN MARKDOWN, SEE IT BEAUTIFULLY • A live editor that renders headings, lists, tasks, tables, callouts, highlights, maths and diagrams as you type, while the file stays plain text. • A formatting bar just above the keyboard, and Writing Tools that keep your links and structure intact. • Wikilinks, embeds, backlinks, tags and a graph of how your notes connect. • Search every note instantly, including handwriting on your canvases. • Daily notes, a calendar, tasks gathered from every note, templates and a board view. DRAW WHEN WORDS WON'T DO • Canvases for sketches and diagrams, with Apple Pencil on iPad, beside cards and links to your notes. • Opens JSON Canvas and Excalidraw drawings. WORKS WITH YOUR MAC — AND OFFLINE • Keep a notebook in iCloud Drive ▸ Igneous and it's on all your devices. • Or pair with Igneous on your Mac over your own network: the phone keeps a full offline copy and sends its edits when it's back. Changes to different lines are combined, and if you both changed the same words, both versions are kept. Drawings merge shape by shape. • Nothing ever passes through a server of ours — there isn't one. SHORTCUTS, SIRI AND WIDGETS • Actions for new notes, today's note, tasks, search and voice notes, ready for Shortcuts and Siri. • Home Screen widgets with buttons you choose, Lock Screen widgets, Control Center controls, Focus filters and Live Activities. YOUR NOTES, YOUR FILES Igneous reads Obsidian-flavoured Markdown as written and never adds anything you didn't ask for. Point it at the vault you already keep.
