Todosian is an Android todo app for Obsidian users. It manages todo lists stored as Markdown files inside your vault (or any folder you sync to your phone).

Todosian reads and writes your existing .md files directly. There is no database import, no account, and no built-in sync.

How it works

- Connect a folder using Android's Storage Access Framework (SAF)
- Each Markdown file becomes a category
- Todos use standard Markdown checkboxes: - [ ] and - [x]

Features

- Add / edit / toggle / delete todos
- Create / rename / delete categories (files)
- Optional support for Obsidian Tasks plugin metadata (dates, priority, recurrence)
- Material 3 UI, dynamic color (Android 12+)
- Offline-first and privacy-focused (no analytics)

Notes

- Todosian modifies your Markdown files directly. Keep a reliable backup of your vault/folder.
- Todosian is independent and not affiliated with Obsidian or the Obsidian Tasks plugin.
