How to set a reminder for someone else (and know they did it)

To set a reminder for someone else, you need a tool that sends the message to their phone or inbox rather than yours. Five methods work: a shared calendar invite, a shared list, a scheduled text, a household app, or a reminder service that delivers to any address. The one thing almost none of them do is tell you whether the person actually did it, and that is usually the reason you wanted the reminder in the first place.

Here is how each method works, when it fails, and what to use for which situation.

Why most reminder apps cannot do this

Reminder apps are built for one person. The notification goes to the account holder's own devices, which is exactly the wrong destination when somebody else is the one who needs to remember.

There is no "remind someone else" button in Apple Reminders, Google Tasks, or most consumer reminder tools. Everything below is a workaround for that gap.

Which workaround fits depends less on you than on the other person: what they have, what they check, and what they will agree to install.

Method 1: a calendar invite

Create an event, add their email as a guest, set the alerts. They get an invitation and, if they accept, the event lands in their calendar with its reminders.

Works well for appointments, meetings, anything with a date that both people should see.

Fails when the person does not live in their calendar. Alerts get dismissed, and an accepted invitation tells you nothing about whether anything was done. It shares the information, not the responsibility.

Method 2: a shared list

Apple Reminders and Google Tasks both allow a shared list, and Apple lets you assign an item to a specific person.

Works well for ongoing household lists between people on the same platform. Groceries, chores, the running list of small things.

Fails when the two of you are not on the same ecosystem, or when the other person simply does not open the app. That is the usual case, because the habit you are trying to fix is precisely the habit of not checking.

Method 3: a scheduled text

Both iOS and Android can schedule a message to send later.

Works well for a one-off nudge where a personal tone matters.

Fails when it needs to repeat. There is no recurrence, so you have to reschedule it every time, which means you now have to remember to remind them. The load moved to you.

Method 4: a household app

Family apps bundle a shared calendar, task lists and sometimes meal planning.

Works well for households genuinely committed to one shared tool.

Fails when one person stops opening it, which is generally within a month. Everyone has to install, sign up, and keep the habit.

Method 5: a reminder service that delivers to them

You set the reminder from your own account and enter their address. At the scheduled time, they receive the message directly, with nothing to install and no account to create on their side.

Works well for almost everything, and especially for recurring reminders to people who will not adopt a new app.

Fails when the service only sends. Which brings us to the part everyone skips.

The missing half: knowing it was done

Every method above ends the same way. The message goes out, and then silence.

You do not know whether it was read. You do not know whether anything happened. So you check, or you ask, and asking twice is the thing you were trying to avoid.

A reminder that only goes out solves half the problem. The half that exhausts people is having to verify.

What closes the loop is a single button in the message. The person taps it, you see it. And if nobody taps it, a second reminder goes out and then you are told.

That last part is what turns a reminder into something you can stop thinking about.

Which method for which situation

Setting it up properly

Whatever you choose, four steps make the difference between a reminder that works and one that gets ignored.

Write it in your own words. Not a category. The sentence you would actually say to them.

Use their time zone, not yours. If they are in another country, the reminder should arrive at their nine in the morning.

Let them agree once. Sending reminders to someone who never accepted is how you end up ignored or filtered as spam. One confirmation, once, is enough.

Decide what happens on silence. The step everyone skips, and the only one that lets you stop checking.

When the reminder is private

Not everything is everyone's business. A message on a locked screen is read by whoever is standing nearby.

If the subject is private, the message should say that it is time without saying what for. A neutral sentence, or a single word only the two of you understand, is enough.

Common questions

Can I add a reminder to someone else's phone?

Not directly. You cannot write into another person's reminder app unless they share a list with you. The practical route is a service that sends them the message at the scheduled time, so nothing has to be installed on their side.

How do I send a recurring reminder to someone else?

Set it once with a schedule, daily, weekly or monthly, and enter their address as the recipient. It then goes out on its own, without you having to think about it again.

Does the other person need an account?

They should not. If a tool requires the recipient to sign up, you have moved the effort onto the person doing you a favour.

What if they ignore it?

That is what a follow-up is for. One reminder can be missed honestly. A second one, followed by a note to you, means you find out the same day rather than a week later.

Is this not just automated nagging?

It is the opposite. Nagging is you asking, repeatedly, and both of you resenting it. This is a system asking once, quietly, so you never have to be the one who asks.

In short

Five methods can send a reminder to someone else. Only one kind tells you whether it landed.

If the reminder matters, choose the one that answers back.
