How to Share a Task List Between iPhone and Android

You can share a task list between iPhone and Android with Microsoft To Do. Install To Do on both phones and sign in with separate personal Microsoft accounts. Microsoft also supports list sharing within the same work or school organization. If you use a work account on one phone and a personal account on the other, use a supported account combination before setting up the list. Microsoft To Do setup · Supported sharing scenarios

Create a shared list and send one invitation

In this example, Ana has an iPhone, and Mateo has an Android phone. They are preparing for a neighborhood book swap. Ana owns the shared list, and they each use their own personal Microsoft account.

1. On the iPhone, Ana opens Microsoft To Do and creates a new list called Book swap.
2. She opens that list, taps the sharing icon, and chooses Create Invitation Link. She copies the link and sends it directly to Mateo.
3. Mateo opens the link on Android, signs in with his own personal Microsoft account if prompted, and joins the list. He opens To Do and confirms Book swap appears.
4. Ana checks the member list. Once Mateo has joined, she opens sharing again and selects Manage access → Limit access to current members to close the invitation to new members.

Create a fresh list for this purpose so both people know exactly what they can see. Keep unrelated reminders and private notes in separate lists that you have not shared. If you later use Stop Sharing, existing members lose access. Create and share lists

Make one change from each phone

Ana adds Collect donation boxes, gives it a Thursday due date, and assigns it to Mateo. Mateo checks that the item appears, opens its details, and adds a note that the boxes are ready after 4 p.m. Ana checks the note on her iPhone. Mateo then creates Print table signs and assigns it to Ana. Ana checks it off after printing and Mateo verifies the completed status from Android.

To assign a task, open its detail view, choose Assign to, and select a person who joined the list. When a shared list includes an old private item by mistake, move or remove it promptly and check visibility from the other account. Moving assigned tasks between lists clears their assignments, so review the assignee after moving one. Assign tasks in shared lists

Test due dates and notifications separately

A due date says when the task is due. For a timed prompt, open the task and set a reminder. Check the date from both phones, and have the intended recipient verify their reminder on their own device. To test shared-list activity alerts, turn on To Do notifications in the phone settings and make a fresh assignment or completion from the other phone. Microsoft documents notifications for particular shared-list events, so test the exact event you rely on. On Android, Microsoft's documented push setup requires a Google account connected in device settings. Due dates and reminders · Shared-list notifications

If the other person cannot join, confirm which account opened the link and whether the owner already limited access. If edits appear but notifications do not, check operating-system permissions and Focus or Do Not Disturb settings on the receiving phone, then test a fresh assignment. Both people should be able to edit and complete a sample before relying on the list for something time-sensitive.

This setup follows Microsoft documentation checked November 10, 2026. If you also want a broader personal planner, see the iPhone planner guide and Android planner guide.
