Best shared to-do list apps for couples (2026)
Most couples don't need a heavyweight productivity system. They need one shared list that both people actually open. Here's an honest look at six options, including our own, and who each one suits.
A fair warning: we make TickOff, so we're not a neutral party. We've tried to describe every app fairly, using what the companies themselves say. Apps change, so check the details before you commit. Last checked October 2026.
Sharing with a whole family or a work crew rather than one partner? See our wider comparison of the best shared to-do list apps for families and teams.
Start with three questions
- What phones do you each use? If you're both on iPhones you have more options than if you're on mixed devices.
- What are you actually sharing? Tasks and reminders, groceries, a calendar, or all three?
- How much structure do you want? Some people want projects, labels and filters. Most couples want a list and a reminder.
At a glance
| App | Best for | Free? | The catch |
|---|---|---|---|
| Apple Reminders | Couples who are both fully on Apple devices | Free, built in | Sharing is built around Apple Accounts and iCloud |
| Microsoft To Do | Simple shared lists, especially if you already use Microsoft | Free | You need a Microsoft account |
| Todoist | People who like organising with projects and labels | Free plan with limits | More to learn; the free plan caps projects and collaborators |
| Cozi | Families who want a shared calendar first | Free, with ads | Built around the family calendar rather than tasks |
| AnyList | Shared grocery lists and recipes | Free to start, paid extras | Built for food, not general tasks |
| TickOff | Couples and small crews who want assigned tasks and reminders | Free for up to 3 people and 30 active tasks | Newer and smaller; no app-store listing |
Apple Reminders
If you're both on iPhones, start here. It's already on your phones, it's free, and shared lists work well. Apple describes sharing as being with other iCloud users, so each of you needs an Apple Account. If one of you is on Android there's no Reminders app for you. The best you can do is sign in to iCloud.com in a browser, and Apple's own help notes that with the newer Reminders you might not see all your shared lists there and can't manage sharing on the web. For mixed-phone couples, see our guide to shared reminders on iPhone and Android.
Microsoft To Do
A free, straightforward task app from Microsoft, with apps for phones and a web version. You share a list by sending an invitation link, and the people you share with can view and change it. You'll need a Microsoft account. A good pick if you already live in Outlook and Microsoft 365.
Todoist
A powerful organiser with projects, labels and filters. On Todoist's free plan you can have up to five personal projects and share each one with up to five people, which is plenty for a couple. The trade-off is that there's more to learn, and some features sit behind a paid plan. A good choice if you like building a system, and heavier than you need if you just want a shared list.
Cozi
Cozi is a family organiser built around a shared calendar, with shared shopping and to-do lists and a recipe box. The free plan includes those, with ads; the paid plans remove the ads and add extras such as more event reminders. A good fit if the calendar is your main need.
AnyList
AnyList is built for grocery lists and recipes. Lists update instantly for everyone sharing them, and the optional Complete subscription adds things like recipe import from websites, a meal-planning calendar and store filters. It's excellent for food, but it isn't a general task manager.
TickOff
Ours, so weigh this accordingly. TickOff is a shared to-do list built for two people or a small team: you assign each task to a person (or both), reminders go to whoever owns the task, and tasks can repeat. It works in the browser and installs to your home screen on iPhone and Android, with no app store needed. The free plan covers up to three people and 30 active tasks; Pro adds AI quick-add, photos, calendar sync and reports.
The catches: it's newer and smaller than everything else on this list, there's no app-store listing, and it doesn't have a family calendar view. If a shared calendar is your main need, look at Cozi.
How to choose
- Both on Apple and want zero setup: Apple Reminders.
- Mixed phones and you want it simple: Microsoft To Do or TickOff.
- You love organising things: Todoist.
- The calendar is the main event: Cozi.
- Groceries and recipes: AnyList.
Whichever you pick, what matters most is that you both use it. Choose one, run it for two weeks, and only then decide whether it's working.
Common questions
Is a shared to-do app better than a shared note?
For one-off lists, a note is fine. A to-do app earns its place when tasks have owners, dates or reminders, because a note can't remind anyone of anything.
Can we use more than one app?
Many couples do: one for food (such as a grocery app), one for a shared calendar and one for tasks. Just avoid keeping the same thing in two places.
