The Obsidian Things3 Sync plugin allows seamless synchronization of todos, tags, and dates between Obsidian and Things3. It works cross-platform on macOS and iOS, and supports multiple languages for creating todos. Users can easily create or toggle todos in Things3 directly from Obsidian, with tag support tied to Things3's existing tags. Dates in Obsidian notes are also transferred to Things3. Additionally, each todo created in Things3 includes a backlink to the corresponding Obsidian note.

The Things3 Today plugin allows users to seamlessly integrate their task management from the Things3 app into their Obsidian workspace. It displays the 'Today' list directly within Obsidian and provides features to mark tasks as completed with a single click. The plugin automatically refreshes the task list every 30 seconds to ensure the tasks are up-to-date. With its clean interface, users can efficiently manage their tasks while keeping their note-taking workflow in Obsidian intact.
