A Chinese app titled “Are You Dead?” (Chinese: Sileme) went viral, briefly topping the paid app charts on the Apple App Store in China and several other countries.
What is the app?
Developed by a small team of three Gen Z founders, the app is a minimalist safety tool designed for the growing population of people living alone. It serves as a “digital proof-of-life” system.
How does it work?
Users must open the app and tap a large green button once every one or two days to confirm they are alive.
Emergency Alerts
If a user fails to check in within the prescribed timeframe, the app automatically sends an email notification to a designated emergency contact, alerting them that something may be wrong.
The Name
The original name, Sileme, is a dark-humor wordplay on the popular Chinese food delivery giant Ele.me (which means “Are you hungry?”).
Rebranding to “Demumu”
Following its sudden surge in popularity and criticism that the name was too blunt or offensive particularly for elderly users, the company announced on January 14, 2026, that it would rebrand to Demumu for its global version.
The “De” in the new name is derived from the English word “death,” while “mumu” was added to sound more “friendly” or “cute.”
Social Context
The app’s success highlights the “loneliness epidemic” in China, where an estimated 125 million to 200 million people live in one-person households.
Users have stated that they use the app because they fear dying alone unnoticed, wanting to ensure their bodies are found with “dignity.”
