Why people do not show up
They meant to. Then the day happened. The invite was three weeks ago, the reminder was one email among dozens, and at 6:40 on a Thursday the couch was right there. Nothing told them, at the moment it mattered, that it was time to put shoes on.
The numbers are worse for free events. Across check-in data from more than 1,070 live events, the event-software company PheedLoop found a median no-show rate of about 20%: about 28% for free events and 17% for paid ones, and about 32% at small events of 10 to 49 people. That small free event is exactly the book launch, the run club social or the founders' breakfast most people host.
Reminders work, and timing and wording matter
There is good evidence that a reminder at the right moment changes behaviour. A Cochrane review of randomised trials found text reminders raised attendance at healthcare appointments from 67.8% with no reminder to 78.6%. In two NHS trials with about 10,000 outpatients each, a text that named the specific cost of missing ("Not attending costs NHS £160 approx.") cut missed appointments from 11.1% to 8.4%.
An event is not a clinic appointment, but the lessons carry: remind people close to the moment, and say something specific.
Ring them at the right moment
| Event | When to ring | What the alarm's name says |
|---|---|---|
| In person, across town | Two hours before | "Supper club, 8pm, leave by 7:15" |
| In person, nearby | An hour before | "Doors 7, side entrance" |
| Online | At the start | "Live now, join the call" |
| Morning event | The wake-up itself | "Breakfast 7:30, Elm St" |
The name and wallpaper show on the ring screen. The creator's note holds the rest (which entrance, what to bring, the dress code), and the call-to-action link opens a map, a ticket or a stream when people answer.
Three hosts, three fixes
The free monthly meetup. Asha runs a 40-person design meetup on Luma. Typically a third of the list does not come. She pastes the Luma link into LFG Alarm, sets it to ring an hour before doors, and adds the alarm link to the event description and her last blast. The number of people riding the alarm becomes her real headcount for pizza. See How LFG Alarm adds to Luma.
The house party. Jamal's Partiful says 30 going. He knows that means 18. He makes the alarm from his Partiful link for two hours before, with the party's song on it, and puts the alarm link in a text blast: "ring at 7, first one through the door gets the good seat". See How LFG Alarm adds to Partiful.
The online launch. A small studio is going live on a stream at 6:00 PM London time and has people in five countries. One public alarm rings everyone at 6:00 London time, in the same second, and each person sees it in their own time zone.
Make it something people want
An alarm should not feel like a nag. Put the event's hype video or song on it, let Rocco roast a snooze, and give a small prize of your own to whoever answers first; the wake board shows who that was. A mystery alarm keeps a video or message sealed until it rings, which is a good way to reveal a surprise guest or a secret location.
How loud it is
Time and event alarms are real alarms on both phones: on iPhone they use Apple's own alarm system and ring through silent mode and Focus; on Android they take over the screen even when the phone is locked.
Works with the tools you already use
- Partiful or Luma: paste the invite link and the alarm is made from it. See How LFG Alarm adds to Partiful, to Luma, and getting party guests to show up.
- A group chat: post the alarm link there. See getting a group chat to commit.
- An AI agent: it can make and share a time alarm for the event. See your AI agent with Gmail and calendar.
- A whole community: see the community rally kit.
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 public alarm for 5:30pm this Thursday called "Doors 6:30, side entrance", with "MEETUP TONIGHT" drawn on the wallpaper, and give me the link for the event page.
Already have the LFG Alarm app and connected it to your AI agent?
Why it works. A public alarm lets every guest join from one link and get rung an hour before doors, with the one fact people ask for on the ring screen. Add the creator's note and the map link in the app; an AI agent cannot set those yet.
Common mistakes
- Ringing at the start time for an in-person event. People need time to get there. Ring one or two hours before.
- A vague name. "Reminder" says nothing on a ring screen. "Doors 7, side entrance" does.
- Changing the time after people join. Once someone rides an alarm, its time is fixed. Change the creator's note for small updates, or make a new alarm.
