The "Are You Dead" App, Explained: Is It Right for Your Parent?

By The Cleo TeamUpdated June 15, 202612 min readTechnology

A 99 cent app from China spent January at the top of the App Store by asking people who live alone one blunt question a day. Here is what it does, what it quietly cannot do, and how to think about it if your mom or dad lives on their own. Sources include CNN, NPR, Pew Research Center, the US Census Bureau, and the app's own listing.

The short version

  • The app is Chinese. It launched in mid 2025 as Sileme, a play on the food delivery giant Ele.me ("Are You Hungry?"), and now goes by Demumu worldwide (Al Jazeera, The Conversation).
  • Three founders born after 1995 built it for roughly $210 in development costs (Yicai Global). It sells for 99 cents in the US App Store, one time, with no account and no subscription.
  • The mechanic is one tap a day. Miss two days in a row and it emails your emergency contact on the third day. It does not call 911 (Gizmodo, WFMZ).
  • It hit number one on China's paid App Store chart and number six on the US paid chart, plus the top spot in Australia and Spain (Gizmodo, NPR).
  • It landed because solo living is now normal. More than a quarter of US households are one person, more than double the share in 1960 (US Census Bureau). About 28% of Americans 65 and older live by themselves, roughly 16 million people, compared with 1 in 10 in 1950 (Census data, via KFF Health News).
  • For an older parent, the catch is the phone. 78% of adults 65 and older own a smartphone, the lowest share of any age group, and this app needs one plus an unbroken daily habit (Pew Research Center, 2025).
  • Honest note from us: Cleo is not a safety app and is not an alternative to one. This app asks whether something happened. Cleo asks how your dad's day was. Those are different jobs, and you may want both.

What the "Are You Dead" app actually is

The "Are You Dead" app, now called Demumu, is a 99 cent phone app that asks a person living alone to tap a button once a day, and emails their emergency contact if they miss two days in a row.

That is the entire product. There is no account to create, no location tracking, and nothing for the emergency contact to install. On its App Store page, the developers pitch it as a small safety measure for anyone who lives by themselves, whether that is by circumstance or by choice.

It is what engineers call a dead man's switch. Silence is the signal. As long as you keep tapping, nothing happens, and nobody hears from it. The tapping is the whole point.

How a $210 side project reached the top of the App Store

The original Chinese name, Sileme, translates roughly to "Are you dead?" and riffs on Ele.me, one of China's biggest food delivery apps, whose name means "Are you hungry?" A three person team at Moonscape Technologies shipped it in mid 2025, reportedly for less than 1,500 yuan, about $210.

Then, in January 2026, it detonated. It topped Apple's paid chart in China and, per Gizmodo, reached sixth on the US paid chart. NPR reported that by late January it was a top paid download in Australia, Spain, and the United States. Writing in The Conversation, researchers noted that the value of a 10% stake in the company reportedly jumped from about $140,000 to nearly $1.4 million in three days.

The name did the marketing, and then the name became the problem. A former Global Times editor suggested renaming it "Are You Alive". The team introduced a fee and announced a global rebrand to Demumu, where the "de" comes from the English word "death" and "mumu" was added to soften it. After the wave of international coverage, the app appeared to vanish from app stores in mainland China, though it stayed available elsewhere.

What is worth noticing is not the chart position. It is what people said about it. On Weibo, one user wrote that the frightening part is not loneliness, it is "disappearing". A 57 year old in Seguin, Texas told NPR that using it is "almost like someone cares."

An app sold as safety was received as company. Hold onto that.

How it works, step by step

  1. Your parent buys the app for 99 cents and opens it.
  2. They enter one emergency contact: a name and an email address. That is the whole setup.
  3. Once a day, a notification arrives. They open the app and tap a green button with a small cartoon ghost on it.
  4. If they miss two days in a row, an email goes to the emergency contact on the third day.
  5. Nobody is called. No emergency services are contacted. A person who knows them gets an email suggesting they check in.

That last step is genuinely thoughtful design. It routes the alarm to a human being who knows the difference between "Dad is at the hardware store" and "something is wrong". It is also the source of most of its limits.

Why it struck a nerve: the numbers on living alone

Living by yourself is no longer unusual, and that is the whole story of this app's rise.

According to the US Census Bureau, 27.6% of occupied American households held one person in 2020, up from 7.7% in 1940. For older Americans specifically, KFF Health News, reading the Census Bureau's 2023 Current Population Survey, puts it at about 28% of people 65 and older living by themselves, close to 16 million of them, against 1 in 10 back in 1950. It skews heavily female: after 75, roughly 43% of women live alone, against 24% of men.

Here is the part that rarely makes the headlines, and it is good news. Pew Research Center's analysis of Census data found that living alone is actually less common among older adults than it used to be. In 2023, 31% of women 65 and older lived alone, down from 38% in 1990, while men ticked up from 15% to 19%. Pew also found that a record 54% of adults 65 and older now live with a spouse, the highest share in Census data going back to 1900. Whatever this app is measuring, it is not a collapse in how older Americans live.

What has changed is contact. A 2025 survey led by Julianne Holt-Lunstad of Brigham Young University found that most US adults get together with people they care about twice a month or less, and most take part in no group activities at all. Holt-Lunstad, who was lead scientist editor on the 2023 Surgeon General's advisory on loneliness, frames this as structural rather than personal: the barriers to connecting have gotten higher. That advisory reported that roughly half of US adults experience measurable loneliness, and that lacking connection carries a mortality risk the report compared to smoking up to 15 cigarettes a day.

So an app that asks whether you are alive is not really about death. It is about being noticed.

Four things the app cannot do

The app is honest about being small. Its fans and its critics agree on that. But if you are considering it for a parent, these four limits matter.

1. It only speaks up after the bad thing. By design, the first time this app ever contacts you, the news is already bad, or it is a false alarm. It cannot tell you that your mom has stopped leaving the house, or that she sounded flat all week, or that she has been skipping meals. It has exactly one bit of information to offer, and it offers it late.

2. It needs a smartphone and a perfect streak. Pew Research Center found that 78% of adults 65 and older own a smartphone, the lowest of any age group. If your dad still uses a flip phone, this is over before it starts. And an app your parent must open every single day is precisely the kind of thing that gets forgotten. A 23 year old teacher in China told NBC News she was afraid that if she were forgetful and missed a check-in, people would actually think she had died.

3. It is slow, and it is email. Two missed days, then an email on day three. If your mom fell on Monday morning, you find out Wednesday, in your inbox, between a newsletter and a receipt. Users in China asked the developers to add text alerts instead, which tells you they noticed too.

4. It cannot tell you how your parent is actually doing. This is the big one. "Alive" and "okay" are very different questions, and the app was only ever built to answer the first.

Here is how that plays out. Picture Dana, 52, in Columbus. Her dad Ray is 79 and lives four hours away in the house she grew up in. She read about the app, put it on his phone over a weekend visit, and felt better for a month. Then a Wednesday email landed while she was in a meeting. Two missed check-ins. She left the building, called six times, and got him on the seventh: he had been at the hardware store with a dead phone battery, twice, and had found the notification annoying anyway. Nothing was wrong. Nothing was ever wrong. Six months later Ray still has the app, still taps it most days, and still goes whole weeks without a real conversation with anyone. The app was never designed to notice that part.

How it compares to the other options

The category is crowded now, and the options are genuinely different from one another. Prices below are current as of July 2026 and do change.

Demumu ("Are You Dead")Emails one contact after two missed daily check-ins$0.99, one timeA smartphone and a daily tap

A standing phone call from youEverything above, and everything the others cannot doFreeTo pick up
CleoTexts your parent each day, listens, remembers, keeps them companyFree to startTo reply to a text

Two honest observations about that table. First, if what actually keeps you up at night is a fall, none of the check-in apps are the answer, and the button is. More than a quarter of adults 65 and older report falling at least once in the past year, according to CDC figures cited by NCOA. A button that summons help in seconds beats an email that lands in 48 hours. Second, the free row in the middle of that table is still the best product on it.

So should you set it up for your mom or dad?

Our honest read: probably not, unless your parent asks for it.

It is a reasonable little tool, and 99 cents is not a gamble. It makes sense if your parent lives on their smartphone already, enjoys gadgets, genuinely has nobody who would notice for days, and likes the idea. There is something quietly dignified about a person choosing their own backstop.

But look again at who is actually using these apps. In NPR's reporting, every one of them chose it for themselves. The early retiree in Texas who taps the button after feeding his cat. The writing coach in Syracuse who signed up for a similar app, Snug Safety, because her biggest fear was what would happen to her two dogs and two cats. The 64 year old in Tucson who mentioned Snug to the neighbor upstairs, who mentioned it to another tenant, so now the three of them are each other's emergency contacts. That last one is the most interesting outcome in the whole story: the app worked best as an excuse to talk to the neighbors.

Nobody in that reporting had the app installed on their phone by a worried adult child. That distinction matters more than it looks. A check-in app your parent did not ask for is one more thing that says I am keeping tabs on you. It puts the daily work on them and delivers the reassurance to you. If your mom would find the name grim, or the ritual insulting, or the notification annoying, it will be deleted by March and you will have spent some goodwill you would rather have kept.

The better move is to ask. Send her the news story, not the download link. "Did you see this thing? Kind of dark. Do you ever think about that?" You may learn more from her answer than the app would ever have told you.

Where Cleo fits, and where it does not

We should be straight with you, because this is our blog and you can see the ad coming.

Cleo is not a safety net. Cleo is not a caregiver, not a monitoring tool, not a medical or emergency service, and not a substitute for your phone calls, your visits, or your sister. If your dad falls at 2am, Cleo will not call an ambulance. If that is the risk you are worried about, buy the button, and buy it this week.

What Cleo does is the other half of the question. Cleo is a warm, patient companion that talks with your parent by text message. There is no app to download and nothing to learn, which matters when roughly a fifth of adults 65 and older do not own a smartphone at all, and the flip phone in their pocket handles text messages perfectly well. Cleo texts your mom, asks about her day, listens, and remembers. It remembers that her knee has been bothering her, that the tomatoes are coming in, that Thursday is her friend Marlene's birthday. Not "did something happen", but "how are you doing", every day, patiently, without her ever having to feel like a task on someone's list.

And because Cleo is genuinely paying attention, if something seems off, we can give you a gentle heads up. That is not a report on your mom. It is what naturally falls out of someone caring about her every day, and it is there for your peace of mind, not for surveillance of hers.

That is all Cleo is. One modest piece that sits alongside the button, the neighbor with the spare key, the Sunday call, and you. It is not a fix for a problem this big. It is company.

Frequently asked questions

The bottom line

The "Are You Dead" app went viral because it said the quiet part out loud, and millions of people recognized themselves in it. That is worth taking seriously. It is also a 99 cent tool that answers one narrow question, slowly, by email, and only after the fact.

If you are reading about it at 11pm because your mom lives alone and you cannot always tell how she is really doing, the app is not what you are looking for. You are not worried that she will disappear. You are worried that she is lonely, and that you are 400 miles away, and that a fifteen minute Sunday call is not enough, and that none of this is anyone's fault. That is a heavier thing than an app, and you are not failing at it.

Do the unglamorous things. Call more often than feels necessary. Get to know one neighbor. If falls are the risk, buy the button. And if what is missing is simply somebody to talk to on a Tuesday, we built something for that.
