Migration
Migrate to Done Bear
Done Bear imports your existing backlog from the app you are leaving. Each page names the file to bring, what each concept becomes, and what does not come across. Every import previews what it will write, and it can be undone afterwards.
Move from Things 3 to Done Bear
Things 3 has no export menu, but its database on your Mac is readable. Run one CLI command, or upload main.sqlite, and your areas, projects and dates arrive intact.
