You find a link worth saving. You read a quote worth keeping. You discover a band worth remembering. By the time you switch apps, find the right file, and paste it in — you've lost your train of thought. AppendX gives you two ways to get it down. Share from any app on your iPhone, or open AppendX and capture a thought that isn't on screen anywhere. Either way it lands in exactly the right markdown file, formatted exactly how you want it. SMART TARGETS Set up your destinations once — a file for books, one for links, one for ideas. Each with its own emoji, format, and file. AppendX reads your files' headings to name targets automatically, and suggests icons as you type. LISTS, BLOCKS, OR YOUR OWN FORMAT Capture as a clean list item that adapts to whatever you share, a block that keeps every piece of data, or build a custom template with tokens. A live preview shows exactly what will land in your file — before you commit. PASTE AS MARKDOWN Copy a paragraph from the web and paste it into AppendX. Bold stays bold. Links stay links. iOS hands most apps plain text and drops the formatting — AppendX reads the clipboard's HTML instead, so what you copied is what you keep. TYPE, TALK, OR PASTE Capture mode opens straight to a text field. Type it, dictate it with the keyboard's microphone, or paste formatted text from anywhere. SMART CAPTURE Different apps share data differently — AppendX sorts it out. Clean URLs with tracking junk stripped. Real titles instead of bare hostnames. Selected text recovered even when apps bury it in odd places. What you meant to save is what gets saved. NEVER LOSE DATA Every capture is queued locally before it's written. If iCloud hiccups, your capture waits safely and syncs when your files are reachable. A full history shows everything you've captured and its status. WORKS WITH YOUR SETUP Any app that stores markdown files: Obsidian, iA Writer, 1Writer, or a plain folder. iCloud Drive or on-device storage. No account, no analytics, no server — your notes never leave your control. Free, with an optional tip jar if it earns a place in your routine.

Cairn is a fast, native task and note companion that lives on top of the Markdown files you already own. Point it at your Obsidian vault — or any folder of Markdown notes — and your tasks and notes appear in clean, focused views. Everything you do in Cairn is written straight back to your files as plain text, in the Obsidian Tasks format. YOUR NOTES STAY YOURS • No account, no sign-up, no Cairn cloud database — your tasks live in your own files • Cairn does not send your notes or tasks to the developer • Careful, patch-based edits change only the content you touched, preserving the rest of your note • Works alongside Obsidian, iCloud Drive, Git, or any sync you already use CAPTURE, BROWSE, AND PLAN • Browse and edit Markdown notes directly in your vault • Quick capture into your daily note, with date, tag, and priority tokens parsed as you type • Choose where longer captures are saved • Today, Upcoming, Inbox, and Pool views, plus a global filter for folders, tags, dates, priority, and status • Full support for sub-tasks and task hierarchies • Recurring tasks in Obsidian Tasks format, with safe completion handling • Convert upcoming calendar events into tasks, or mirror your dated tasks into a calendar you choose (optional) STAY ON TRACK • Local reminders for due tasks — including sunrise-relative reminders computed entirely on your device • A Live Activity keeps today's progress on your Lock Screen and in the Dynamic Island • Home Screen widgets and a Control Center quick-capture control • Search across every task in your vault MADE FOR OBSIDIAN — NOT ONLY OBSIDIAN Cairn reads and writes the Obsidian Tasks plugin format (due, scheduled, start, and done dates, priorities, recurrence, tags), so your vault stays fully compatible with your desktop setup. Don't use Obsidian? Create a plain task folder in the Files app and Cairn works as a stand-alone Markdown to-do app. Cairn asks for access only to the folder you pick. Calendar access and location (used to compute local sunrise times) are optional and processed on your device. If you choose iCloud Drive or another Files or calendar provider, that provider's own sync and privacy terms apply.
