No. It does not pick a time for you. It makes the time you picked hard to forget.

What if the plan changes?

Update the creator's note for small changes, like the room or the meeting point. For a new time, make a new alarm and post the new link: once people have joined, an alarm's time is fixed, so nobody is woken for something they did not sign up for.

Can people outside the chat join?

Only if they get the link and the alarm lets them in. A friends alarm can let anyone with the link ride, or ask you to approve each one. See [Sharing and reach](/wiki/sharing-and-reach).

The app is free to download, and riding someone's alarm is free. See also [how to get people to show up to events](/how-to-get-people-to-show-up-to-events) and [What is a social alarm clock?](/social-alarm-clock).

The fastest way to get a group chat to commit to a time

Why group plans fall apart

"Are we still on for Saturday?" turns into forty messages, three polls and a sticker. Someone says "down", someone reacts with a thumbs up, and two people never reply at all. By Saturday afternoon the plan exists only in a message 300 lines up, nobody is sure whether it was 7 or 7:30, and the one person who made the booking is now texting everyone one by one.

The plan rarely fails because people do not want to come. It fails because nobody owns the reminder, and "down" in a chat costs nothing to say.

Make the plan an alarm

Pick the time and make the alarm, named with the plan: "Mario's, Sat 7pm".
Post the link in the group chat: lfg.gm/a/<alarm-code>.
Watch who joins. Every person who taps it is riding the alarm, which is a clearer yes than a thumbs up. See Riding an alarm.
It rings everyone as a heads-up: two hours before a night out, so people get ready and head over, or at the start for something online, so everyone hops on at once.

If the plan is on Partiful or Luma, paste the invite link into LFG Alarm and the alarm is made from it, with the event's name, picture and start time. See How LFG Alarm adds to Partiful and to Luma.

Three plans, start to finish

The birthday dinner. Ten people, a table for 7:30 that the restaurant gives away at 7:45. Kofi makes a friends alarm for 6:00 called "Ama's bday, Mario's 7:30" and posts it. Eight people join; he now knows to call the restaurant about two seats. The address goes in the call-to-action link, which opens a map when people answer, and the creator's note says "we're splitting the cake, bring cash".

The watch party online. The final kicks off at 3:00. Lena makes an alarm for 2:55 and posts the link in the group's Discord. At 2:55 every phone that joined rings; the voice channel goes from two people to eleven in a minute.

The Sunday five-a-side. The pitch is booked weekly and someone always forgets. One repeating alarm at 9:00 on Sundays, "Pitch at 10, bring bibs", and the group stops having the Saturday-night "are we on?" conversation altogether. To save the same people once and reuse them, make a group in Settings > Friends > Groups. See the fastest way to make a group alarm.

What the alarm can carry

A name and wallpaper that show on the ring screen: the plan in a few words.
A creator's note: the address, what to bring, the dress code. People see it when they open the alarm. You can change it even after people join, so "we moved to the back room" can go up on the night.
A call-to-action link that opens when people answer: a map, a booking, a stream.
A sound or voice picked for the occasion.
A mystery alarm: its video or message stays sealed until the second it rings, which is good for a surprise venue reveal.

Across time zones

A shared alarm rings everyone at the same moment by default, and each person sees it in their own time, so a call between London and Los Angeles needs no maths. See Time alarms.

How loud it is

A time alarm or an event alarm is a real alarm on both phones: through silent mode and Focus on iPhone, and full screen on Android even when locked. That is the difference from a chat message, which waits until someone opens it.

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 make a friends alarm for 6:00pm this Saturday called "Ama's bday, Mario's 7:30", with "DINNER 7:30" drawn on the wallpaper, and give me the link to post in our group chat.

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

Why it works. It sets the time, the plan and what the ring screen says, and the joins tell you who is actually coming.

Common mistakes

Posting the link and then a poll. Pick the time first. The alarm is the decision.
Ringing at the start time for something in person. Nobody can get across town in zero minutes. Two hours before is the default that works.
Changing the plan by editing the alarm. Once people have joined, the time is fixed. Make a new alarm and post the new link.
