@tylersuits@productive_will The data is actually all local. Export from the task app to Obsidian is very easy. However, two-way sync may not be possible.
Web page in Obsidian allows you to perform operations. After modification, it automatically generates an Obsidian document. What do you think?
@tylersuits@productive_will I've developed a task management app similar to Things 3. It has web, Mac, iOS, Android, and Windows versions. If you want to display tasks in the sidebar, you can just open the web version using Obsidian's web view.
