Check-in apps for people who live alone: how they work

A guide from FiveClose · 27 October 2026

More people live alone than ever: young professionals, students, people after a divorce, and older people who want to stay in their own home. A check-in app answers one question: if I stopped answering, who would notice, and how soon? This guide explains how these apps work and what to look for.

How a check-in app works

The idea is sometimes called a "dead man's switch". You choose a few people. The app keeps a timer. Each time you show a sign of life, the timer starts again. If it runs out, the app warns you first, and if you still don't respond, it asks your people to check on you.

• Signs of life can be tapping a button, answering a notification, or simply opening the app.
• The timer may be a day, a few days or a week. Shorter catches problems sooner; longer means fewer false alarms.
• The people told are usually family or close friends you chose, not a call centre.

What to look for

1. Little effort. The best check-in is one you would do anyway. If it takes more than a second, people stop doing it.
2. A warning to you first. You should get the chance to say "I'm fine" before anyone is worried.
3. Steps, not one alarm. Telling one person first, then more people later, avoids panic over a busy weekend.
4. Privacy. Location sharing should be off unless you switch it on, and visible only to people you chose.
5. Works for the people you'd ask. Your friends should be able to receive a request by email or message without installing anything.
6. Easy for older people. Big buttons, no password, and someone else able to set it up.
7. Cost. Many check-in features are free; be wary of a paid plan for something you need every day.

The limits

A check-in app is not an emergency service and not a fall detector. It notices silence, which can take hours or days. If you have a health condition where minutes matter, talk to your doctor about a medical alarm or a watch with fall detection, and use a check-in app alongside it. In an emergency, call your local emergency number.

More than safety

The same people who would notice if you went quiet are the ones worth staying close to. The best check-in apps keep you in touch day to day, not only when something goes wrong. See how to keep in touch with friends as an adult.

How FiveClose does it

• Each person has a 7-day timer, restarted by opening the app, tapping "I'm OK", answering a poke, or an "I'm OK" button in a notification or email.
• Two days before it runs out, you are emailed. If you still haven't checked in, your circle is asked to check on you on days 7, 14, 28 and 49.
• Your friends don't need the app to be in your circle.
• Location is optional, rounded to about 100 m, and seen only by people who have each other in their circles.
• A simple version for seniors, set up by family with a QR code and no sign-in (how to set it up for a parent).
• Free, with no limit on people. Works in any browser and installs on iPhone and Android.
