Cairn
Native task views for Markdown files you already own
Cairn turns Markdown tasks in your Obsidian vault or any folder into fast native Today, Upcoming, Inbox, Pool, and Search views on iPhone and iPad. Every edit is written back to the originalmd file. No account, proprietary database, ads, analytics, or lock-in. Free.
I built Cairn because I wanted the speed of a native iPhone task manager without moving my tasks out of the Markdown files in my Obsidian vault. Cairn reads and writes the original files, so there is no proprietary database or cloud to trust. I’m launching it free, with no account, ads, or analytics. I’d especially appreciate feedback from Markdown and Obsidian users about compatibility and the mobile workflow.
Writing changes back to the original md files instead of hiding tasks in some proprietary store is exactly the kind of restraint I want from a task tool. Obsidian users will appreciate not having to babysit a separate sync layer just to check off groceries.
Finally a tasks app that respects plain markdown and doesn't shove everything into its own database. The Today view on iPad is snappy and edits round-trip back to my vault without a hiccup.
one thing that would make cairn a daily driver for me is recurring tasks with flexible cadences, like every other tuesday or the first monday of the month, written right into the markdown frontmatter so the views just handle it
