Does my co-parent need the app?

Yes, the free LFG Alarm app on iPhone or Android, to be rung.

Can my co-parent see my other alarms?

No. They only see the alarms they ride. Each alarm has its own list of who is on it.

Do we have to be friends in the app?

To add them by name from **Friends**, yes. You can also add someone by email, or send them the alarm's link, `lfg.gm/a/ `.

Can I change the note after it is shared?

Yes. The note can change any time. The time, the title and the sound are sealed once someone joins.

Yes. Time alarms are free, and riding someone's alarm is free.

Is it for emergencies?

No. LFG Alarm is an alarm clock for the moments you plan. In an emergency, call your local emergency number.

Alarm app for co-parents: one alarm a day you both can't miss

Why one alarm, not twenty reminders

A family week is a pile of small handovers: who has the kids tonight, which bag the swimming kit is in, whether the Tuesday swap is still on. Plenty of families run that week across two homes. In the US, more than a quarter of children under 21 have a parent living outside their household, and shared physical custody went from about 13% of divorces before 1985 to about 34% in 2010 to 2014.

Shared calendars and co-parenting apps are good at holding all of it. The trouble is that everything looks the same in them. Research on the "mental load" calls the hidden part of the job anticipating and monitoring: noticing that Thursday is early pickup, and then checking it actually happened. In interviews with 35 couples, that part fell more on women; in a 2015 Pew survey of parents where both work full time, 54% said the mother does more to manage the kids' schedules.

One alarm a day is a small way to share that. Whoever spots the thing sets it. Then neither of you has to remember, and nobody has to send the "just checking you know about..." text.

The days it is for

You already know which ones. They are the ones you would text twice.

The day	When it rings	The note on it
The Tuesday swap	4:15pm	"Swap moved to 5 at the park, Mia has her football boots"
Early pickup	12:30pm	"School closes at 1 today, not 3:15"
The dentist	2:45pm, leaving time	"Dentist at 3:30, Leo's card is in the blue folder"
Costume day	7:15am	"World Book Day, the dragon costume is in the hall cupboard"
Medicine at the other house	8:00pm	"Two spoons after dinner, last dose Friday"
Handing over the passport	9:00am	"Passport goes in Ava's bag before school, flight is Sunday"

Set it for the moment someone has to move, not the moment the thing starts. The dentist is at 3:30; the alarm is for when you need to be in the car.

How it works

Start with your co-parent. In Settings > Friends, tap Create alarm on their row. The alarm starts already shared with them.
Pick the time. Tap ⏰ Time, then Just once, and set the time and the day. They get it in their notifications and tap to ride along.
Write the note. Tap Creator's note in the studio: what is happening and the one detail people forget. You can change the note any time, even after they have joined.
Add a link if it helps. The dentist's page, the school letter, a map pin for the new swap spot. It opens when they answer the alarm.

When it rings, both phones ring. Each of you taps I'm up, so you both know the other saw it, without a single message. If someone snoozes, Rocco roasts them, as gently or as rudely as the chaos level says.

Time alarms ring from the phone itself, with no signal needed. On iPhone they use Apple's own alarm system, which rings through silent mode and Focus; on Android they take over the screen, even when the phone is locked. That matters on the day the other parent's phone is face down in a meeting.

Add the grandparents or the sitter

Some days the person who needs to know is not a parent. Grandma does Wednesdays. The sitter has Friday pickup. Make a group once:

In Settings > Friends, open the Groups tab and tap Create a group.
Call it something like "Leo's people", pick an emoji, and tick your co-parent, both grandparents and the sitter.
On the day, open the group and tap Create alarm with this group.

Only you see your groups, and nobody is told they are in one. Everyone on the alarm needs the free LFG Alarm app to be rung, and riding someone's alarm is free.

Keep it light

This works because it is easy and a little bit fun, not because it is a system. A few things that help:

Take turns. Whoever notices the thing sets the alarm. It is not one person's job.
One a day at most, some days none. If every day has three alarms, they become noise like everything else.
Pick a sound you both like. The studio has hundreds of songs and voices; Your bestie or The butler reads better at 2:45pm than a siren does.
Use the wallpaper. A photo of the costume or the kid's drawing on the alarm screen says more than the title.

Ask your AI agent to set it

If you use an AI assistant such as Claude or ChatGPT with the LFG Alarm connector, it can set the time alarm and add your co-parent for you. Add the note in the app afterwards.

try this

Have your AI agent make it.

Paste this into ChatGPT, Claude, Grok or any AI agent that can add a connector, not into the LFG Alarm app. The setup steps come with it: get the LFG Alarm app, connect it to your agent once, and your agent makes the alarm in your account.

Use LFG Alarm to set a one-off alarm for 7:15am this Thursday called Costume day, make it a friends alarm, add my co-parent [their LFG Alarm username], and write "DRAGON COSTUME, HALL CUPBOARD" on the wallpaper. Give me the link.

Already have the LFG Alarm app and connected it to your AI agent?

Why it works. It sets the time, the person and the words on the screen in one go, so the reminder is right there when it rings.

See Using LFG Alarm from your AI agent for setting it up.

Common mistakes

Setting it for the start time. The swap is at 5; you need to leave at 4:30. Ring at 4:15.
Turning it into the whole calendar. Keep the calendar or co-parenting app for the week. The alarm is the one thing.
A note that says "remember!". Say what and where: "dragon costume, hall cupboard".
Making a repeating alarm for a one-off change. Once someone has joined an alarm, its time is sealed. For a one-day change, make a new alarm; for the weekly swap, a repeating one is fine.
