The Dead Man's Switch: Why China is Obsessed with the "Are You Dead?" App

Daniel Wood

Overview

In early 2026, a simply coded app shot to the top of China's paid iOS charts. Its name? "Are You Dead?" (Sileme). The premise is brutal: click a button every day to prove you are alive. If you don't, it emails your loved ones to come find your body. We explore how a dark pun on food delivery became the ultimate safety net for a lonely generation.

We use apps to track our steps, our sleep, and our calories. Now, millions of young people are using an app to track their own mortality. It is the ultimate "set it and forget it" tool—except if you forget it, the app assumes you are a corpse.

The App: "Sileme" vs. "Eleme"

The app's genius lies in its dark humor. In China, the most popular food delivery app is called Eleme ("Are You Hungry?"). This new app is named Sileme ("Are You Dead?").

The mechanics are a classic "Dead Man's Switch." You set a timer—usually 24 or 48 hours. If you fail to open the app and tap the button before the timer runs out, it automatically sends a pre-written message to your emergency contacts. It is designed for the nightmare scenario: slipping in the shower, a sudden medical event, or an accident in a locked apartment where no one visits.

The 200 Million Solitary Souls

Why is this trending now? Because China is facing a "solitude crisis." State media estimates that by 2030, there will be 200 million people living alone in China. This isn't just the elderly; it is a massive wave of young professionals (Gen Z and Millennials) who have moved to mega-cities for work, leaving their support networks behind.

For these "empty nest youth," the fear isn't just dying; it's dying unnoticed. One viral review on the App Store summed it up grimly: "I don't want to be found by my landlord three weeks later because of the smell."

The Rebrand: From Death to "Demumu"

Of course, you can't be too morbid in 2026. Following its explosion in popularity (and some pushback that the name was "inauspicious"), the developers—a three-person team born after 1995—announced a global rebrand.

The app is now known internationally as "Demumu". The "De" comes from "Death," and "Mumu" is added to make it sound cute and harmless. It’s a perfect microcosm of our era: we want to prevent our own lonely deaths, but we want the icon to look adorable on our home screen.

What Then? Digital Dignity

At What Then Studio, we view "Are You Dead?" as the bleakest necessary utility of the decade. It solves a problem that shouldn't exist.

In a world where we are hyper-connected by social media, we are physically isolated enough that we need an algorithm to check if we are breathing. The app isn't just a safety tool; it's a commentary on the collapse of community. When your neighbors don't know your name, your phone becomes your only lifeline.
