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. ## Key features - Native Markdown task and note management - Works with Obsidian vaults or any folder - Quick capture with date, tag, and priority parsing - Multiple task views (Today, Upcoming, Inbox, Pool) - Full support for sub-tasks and recurring tasks - Local reminders and Live Activity integration - Data stays local, no cloud sync required ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/cairn-markdown-tasks/id6786663000/reviews.md ### 5/5 — Awesome app. But bug *2026-08-15* I do not see a place to select the folder in which the new todos are written to. I first selected the folder that I thought was going to be the folder that the tasks were created, but I realized that need to be my vault root. It scrapes all the tasks from across my vault, but I get an error saying that path resolves outside the selected vault. Thanks **Developer response:** Thanks for the kind review and for reporting this. We’ve added an explicit capture destination setting in the current version (1.1.1): open Settings → Capture → Capture Destination, then choose Monthly Inbox, A Specific File, or Today’s Daily Note. For Obsidian, select the vault root first and choose a destination inside that vault. This should also resolve the “path resolves outside the selected vault” error. If it still happens after updating, please contact us through the Support link so we can investigate. ## Frequently asked questions about Cairn ### Does Cairn have ads?
