Task Tree vs Cairn

Task Tree — Organize anything as a tree Task Tree is a simple, powerful task manager built around tree‑structured tasks. Break any goal into projects, tasks, and subtasks — to any depth — and watch progress roll up automatically from the smallest detail to the big picture. Planning a trip, shipping a product, or just keeping a to‑do list? Task Tree keeps everything in a clear hierarchy that's easy to navigate. WHY TASK TREE • Think in trees — Nest tasks as deeply as you need. Big goals become projects; projects break down into tasks and subtasks. • Automatic progress — Check off the leaves and every parent task and project updates its progress for you. • See the whole picture — The Projects screen shows each project's progress, completion count, and due status at a glance. FEATURES • Unlimited subtask depth • Projects with live progress bars and due‑date tracking • Inline due dates with a built‑in calendar • Move a task (and its subtasks) anywhere — or promote it to its own project • Duplicate a task and its entire subtree • Drill‑down and full hierarchy views • iCloud backup & restore — keep your tree safe • Noteholic integration — send a tree to Noteholic, or import a note as a project (indentation becomes your hierarchy) Simple enough for a grocery list, structured enough for a big project. Plant your first tree today.

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.
