A dead man's switch app for people who live alone
That's the whole idea behind a dead man's switch app: something that stays quiet as long as you're fine, and speaks up the moment you can't. You check in each day. If you don't, the people you've chosen are told — automatically.1
Check in, or the people you chose are told
What a “dead man's switch” actually means
A dead man's switch is a control that does its job by being released. On a train, the driver holds a handle; if they let go, the train stops on its own. The safety doesn't depend on someone raising the alarm — it triggers precisely because they can't. The same logic runs a factory press that opens the instant a hand leaves the button, and a radio operator's spring-loaded key.
That's exactly the problem when you live alone. A panic button only helps if you're conscious and able to reach it. But the situations people fear most — a fall, a stroke, a bad night — are the ones where you can't call for help. I'm Alive turns that around: your everyday “I'm okay” is the handle. Stop holding it, and the alert happens for you. Nobody has to notice you've gone quiet and decide to raise the alarm; your own silence is the trigger, and the app does the noticing.
Four steps, and only the last one involves anyone else
Nothing is sent while you're responding. The switch only “fires” when you've gone quiet past your own window.
Pick a daily window that fits your routine. It's the moment you'll tell the app you're okay.
One tap — from the app, the home-screen widget or your Apple Watch. That's the whole action.
A quiet nudge first. Missing it once by accident never sets anything off on its own.
The contacts you chose are notified that you've gone quiet — so someone can check on you.
A missed check-in tells the trusted contacts you chose — never an emergency service.3
Check-in, grace period, then escalation — one rung at a time
A dead man's switch isn't all-or-nothing. It climbs a ladder, and it only takes the next rung when you stay quiet. Here's exactly what happens, in order.3
- 1Your window
You check in — and nothing happens
As long as your daily “I'm okay” lands inside the window you set, the switch stays silent. No one is contacted, no location is shared, nothing is logged for anyone but you. That's the normal day, and it's most days.
- 2The grace period
You're late — so we nudge you, not your people
Miss the window and the first thing that happens is a quiet reminder on your own phone. A check-in you simply forgot never sets anything off by accident — the grace period exists precisely so a busy morning doesn't alarm anyone.
- 3First escalation
Still quiet — the contact you chose is told
If the grace period passes with no response, I'm Alive notifies the trusted contact you named that you've gone quiet, so a real person who knows you can check in. On paid plans this alert reaches your contacts by push, email and SMS.
- 4Wider circle
The escalation widens to the rest of your circle
On Stay Protected and Complete Safety Net you can name up to ten contacts, and the alert steps outward until someone can act. It never calls emergency services on your behalf — the goal is to get a human who cares about you looking in, fast.
You set the window and the rhythm on your safety routine; new to the idea? Start with what a dead man's switch is.
Who a dead man's switch app is for
Anyone who spends long stretches with no one nearby to notice a bad turn. The people who set one up most often are:
People who live alone
If a day goes wrong at home, there's no housemate to raise the alarm. A daily check-in means someone is told within hours, not whenever you happen to be missed.
Older adults and remote seniors
A quiet, one-tap routine gives grown children peace of mind — even a rural or far-away parent — without cameras, sensors in the home, or a monthly monitoring bill.
Lone workers and night shifts
When your work takes you somewhere by yourself — a field site, a late shift, a night alone — a scheduled check-in confirms you finished safely, and flags it to your contact if you didn't.
Solo travelers and adventurers
On a trip alone, no one back home knows your day-to-day plan. A daily “I'm okay” means a missed one is noticed fast — see the solo-traveler setup.
Anyone managing a health condition
If a health event could leave you unable to reach the phone, the switch doesn't wait for you to act. I'm Alive isn't a medical device, but it makes sure your people find out you've gone quiet.
Adult children checking on a parent
You can't call every day, and you don't want to install cameras. A daily check-in they control lets you both relax — you only hear from the app if their “I'm okay” doesn't arrive.
A dead man's switch vs a medical alert, a GPS tracker or Life Alert
All four answer the same fear — “what if something happens and no one knows?” — but they work in very different ways. The dead man's switch is the only one with no pendant, no hardware, no GPS trail and a free tier.
| Dead man's switch app (I'm Alive) | Medical alert / Life Alert | GPS tracker | |
|---|---|---|---|
| What you wear or carry | Nothing — it's the phone you already own | A pendant, wristband or base unit to wear and charge | A tracker fob or a phone with tracking always on |
| How the alarm is raised | Your silence raises it — no button to press | You press the button (only works if you can reach it) | Someone has to be watching the map and notice |
| Who gets alerted | The trusted contacts you chose | A professional monitoring call centre | Whoever is watching your location |
| Location tracking | None on a check-in — shared only during a live SOS or journey | Often GPS-based, varies by device | Continuous, all-day location trail |
| Cost | Free daily check-in; paid plans from $29.99/yr, no hardware | Roughly $25–$45/month plus a device and activation fee | Device cost plus a monthly subscription |
Prefer a human monitoring centre or automatic 911 dispatch? That's what a monitored medical-alert service is for — we'll say so plainly. See dead man's switch vs medical alert and vs a panic button for the full breakdown.3
Your daily check-in doesn't track you2
A check-in records one thing: that you're okay. It carries no location. We share where you are only during a live SOS or an active journey — with the people you've named, and never as a background trail. If you want the details, the Trust Center spells out exactly what the app stores and for how long.
You decide who hears, and how often you check in1
Choose a daily, three-times-daily or weekly rhythm on the safety routines you set, and name the contacts who should be told if you go quiet. It's your switch — you set the trigger, and you can change it whenever your life does.
Arming your dead man's switch takes about two minutes
There's no hardware to buy and nothing to install in your home. Four short steps and the switch is watching.
Install the app on your iPhone or Android phone and create an account. The daily check-in is free forever — no card, no trial clock.
Choose the person who should hear if you go quiet — a family member, a friend, a neighbour. They don't need the app to receive the alert.
Set a daily, three-times-daily or weekly rhythm on your safety routine. This is the switch you're arming, and you can change it anytime.
Put the one-tap widget on your home screen, or check in from your Apple Watch, so the daily “I'm okay” takes a second and never gets forgotten.
Setting it up on iPhone
Install I'm Alive from the App Store (iOS 15+), sign in, and set your daily window. Add the one-tap check-in widget from the home-screen widget gallery, and — if you have an Apple Watch paired on watchOS 9.4 or later — you can tap “I'm okay” from your wrist too. On iOS 17 and up, the widget tap is a real server-confirmed check-in.
Setting it up on Android
Install from Google Play, sign in, and set your daily window — the dead man's switch and the free daily check-in work exactly the same as on iPhone. Add the home-screen widget for a one-tap check-in. To make sure reminders arrive, allow notifications and exempt I'm Alive from battery optimisation in your phone's settings.
One tap counts whether it comes from the app, the home-screen widget or your Apple Watch.4
A dead man's switch, not just a panic button
Both belong in a good safety net. They cover opposite kinds of bad day.
The dead man's switch
Works when you can't act. Miss your check-in and the alert happens without you lifting a finger — the case a panic button can never cover. It's the quiet watchman that only speaks up when you can't.
The SOS button
Works when you can act and need help now. A deliberate hold-to-send behind a confirmation screen, so a pocket press can't alert anyone. Between them, the two cover the day you reach for help and the day you can't.
What a dead man's switch app can't do
A safety net you can trust is one that's honest about its edges. Here's where this one stops — no small print.
It needs your phone on and charged
A dead man's switch app runs on your phone, so your phone has to be powered on and able to reach the internet around your check-in window. Keep it charged, and pick a time you can reliably meet.
It's not a medical device
I'm Alive doesn't diagnose, monitor or treat anything, and it can't detect what's wrong — only that you've gone quiet. Treat it as one layer of safety, not a replacement for medical care.
It alerts your people, not 911
A missed check-in reaches the contacts you chose — never an emergency service or a monitoring centre. If you need help right now and can act, use the in-app SOS or call your local emergency number directly.
It's best-effort, by design
No phone-based safety net can promise a message will always arrive — delivery depends on signal, battery and the people on the other end. It closes the gap between going quiet and someone noticing; it doesn't guarantee a rescue.
Dead man's switch app: common questions
What is a dead man's switch app?
A dead man's switch is a control that works by being released rather than pressed — let go of the handle and it acts on its own. A dead man's switch app applies that idea to personal safety: you check in each day to show you're okay, and if a scheduled check-in passes with no response, the app alerts the trusted contacts you've named so someone can look in on you. I'm Alive is a dead man's switch built for people who live alone, and the daily check-in is free forever on iPhone and Android.
What happens if I miss my check-in?
Nothing fires the instant you're late. You get a gentle reminder on your own phone first, so a check-in you simply forgot never sets anything off by accident. Only if you stay quiet past the window you set does the app notify the contacts you chose that you've gone quiet. It alerts your own people — family, a friend, a neighbour — and never calls emergency services on your behalf.
Is the dead man's switch free?
Yes. The daily check-in and the missed-check-in alert are free on the Check In plan ($0), which holds one trusted contact and can send up to one alert a month if you go quiet, by push and email. Paid plans add more: Stay Protected ($29.99/yr) raises you to up to ten contacts with unlimited alerts and SMS escalation plus a second daily check-in window, and Complete Safety Net ($39.99/yr) adds the 3× Daily routine. Stay Connected & Travel Safely is a $4.99 one-time plan with a higher monthly alert cap than free.
Does the app track my location?
No. Your daily check-in records one thing — that you're okay — and carries no location at all. Location is shared only during a live SOS or an active journey, only with the contacts you've named, and never as a background trail. That's the difference between a check-in and a tracker: this switch watches for your silence, not your movements.
How often do I have to check in?
You choose the rhythm on your safety routine. Free and Lifetime plans get one scheduled check-in a day; Stay Protected adds a second daily window; the 3× Daily routine is part of Complete Safety Net. There's also a deliberately lighter weekly option on the paid plans (Stay Protected and Complete Safety Net) — a rolling seven days from your last check-in, with a couple of gentle reminders and, about two days after it's due, one non-emergency note to a contact. Weekly is lighter monitoring, not the day-by-day escalation of the daily switch.
Can I check in without opening the app?
Yes. On current iPhones and on Android you can add a home-screen widget and check in with a single tap — it's a real check-in confirmed by our server, not just a shortcut that opens the app. iPhone owners can also check in from an Apple Watch. However you tap, it counts as your “I'm okay” for the day.
Is a dead man's switch app the same as Life Alert or a medical alert?
They solve the same fear from opposite ends. A medical-alert service like Life Alert gives you a pendant or wristband to press when something goes wrong, backed by a monitoring call centre and a monthly bill — it works only if you can reach the button and press it. A dead man's switch app inverts that: there's no button to press and nothing to wear, because your everyday check-in is the signal, and going quiet is what raises the alarm. I'm Alive has no pendant, no hardware, no GPS trail, and a free daily check-in — but it's unmonitored, so it alerts the trusted contacts you named rather than a professional dispatch centre. If you specifically want a 24/7 human call centre or automatic 911 dispatch, a monitored medical-alert service is the right tool.
Does the dead man's switch work on Android?
Yes. The dead man's switch — the daily check-in and the missed-check-in alert to your contacts — works on both iPhone and Android, and the daily check-in is free on both. The one-tap home-screen widget works on Android too. (Fall detection, a separate feature, is iPhone-only; the dead man's switch itself is not.)
What happens if my phone dies or loses signal?
This is the honest limit of any phone-based safety net, and we'd rather say it plainly: a dead man's switch app needs your phone powered on and able to reach the internet at some point around your check-in window. If your phone is dead or fully offline when your window passes, your check-in can't be recorded — which, depending on timing, may itself trigger the missed-check-in alert to your contacts. It's best-effort safety, not a guaranteed medical device, so keep your phone charged and pick a check-in time you can reliably meet.
One tap, from wherever you are
Check in from the app, a home-screen widget, or your Apple Watch. The daily check-in is free forever on iPhone and Android. Paid plans add more: Stay Protected ($29.99/yr) brings a second daily check-in, up to ten contacts and unlimited alerts with SMS; Complete Safety Net ($39.99/yr) adds the 3× Daily routine on top.1
