Does Things 3 support collaboration or sharing?

TL;DR: No. Things 3 has no shared projects, no assignees, no team accounts, and no web app, and Cultured Code’s support page says it does not support real-time sharing of to-dos or lists. If you want the Things workflow and need to share projects, you need a GTD app with sharing built in, such as Done Bear.

Things 3 is a single-person app

Things 3 has no shared areas or projects, no way to assign a to-do to someone else, no comments, and no team billing. Things Cloud syncs your devices to your account, and that’s the whole model.

Part of why Things feels calm is that nobody else is in it. Every collaboration feature is also a notification, a status field, and a sync conflict. Leaving them out keeps it quiet.

That’s a fair trade until the work stops being entirely yours.

The workarounds people try

Most people try to bolt sharing on before they switch tools. Sharing one Things Cloud login syncs two people into one database, with no permissions and no record of who changed what. It gets worse with a third person.

Copying tasks into a work tool splits your system in two: the calm personal one and the team one you resent. Every task needs a decision about where it lives, which is the overhead GTD is meant to remove.

Email and screenshots take the task out of the system entirely. Nothing tracks it after that, and the trusted system now has a hole in it.

GTD works because capture is quick and the list is trusted. All three workarounds cost you one or both.

What a GTD app with sharing needs

It keeps what made Things good and adds the sharing Things leaves out.

The five GTD views stay: Inbox, Today, Upcoming, Anytime, Someday. Today should stay a dated list when someone joins, with no board and no status columns. Sharing should take an invite, with no sync buttons and no per-task permissions to set.

Offline still has to work, because a shared app that stops on a plane is a downgrade from Things. Local-first sync keeps tasks on your device and reconciles them in the background, so the app still opens instantly. And there has to be an import, so years of projects and Someday lists don’t get retyped by hand.

Where Done Bear fits

We built Done Bear for people who’ve outgrown a single-person task manager and don’t want project-management software.

It keeps the Things-style GTD structure (Inbox, Today, Upcoming, Anytime, Someday, and a Logbook) and adds what Things doesn’t: a full web app, Windows and Linux apps, real-time shared workspaces, and a CLI, GraphQL API, and MCP server so your tools and AI assistants can work with your tasks.

The import is one command: donebear import things brings your areas, projects, and tasks across. The Things 3 import guide walks through it.

It’s free to start with no credit card (see pricing), and it runs alongside a personal Things setup if you only want to move the shared projects first.

Who should keep Things 3

If your work is solo and Apple-only, keep Things 3. It’s a beautiful app, and switching costs attention.

If you keep wishing a shared task manager felt like Things, stop forcing workarounds through it. Move the shared work to a list built for sharing, and keep the one you trust.

The other walls people hit with Things 3: no Windows version, no Things 3 web version, no Linux build, and no official MCP server for AI assistants.
