An app from China that checks the well-being of users has become popular among young people living alone.

An app from China, launched in May, has quickly gained popularity among young people living alone, with a provocative message: "Are you dead?". It allows users to designate an emergency contact who will be notified if they do not confirm their well-being for several days. At a cost of 8 yuan (approximately $1.14), the app became the most downloaded paid app from the Chinese App Store, but later disappeared for unclear reasons. Co-founder Ian Guo stated that the app was built for less than $150 and is now worth approximately $15 million. The concept emerged from online conversations, responding to a real need for safety in the context of urbanization and demographic changes. Being considered too grim, the initial name of the app was renamed to "Demumu". User reactions are mixed; some find it amusing but impractical, while others see it as a useful solution to increasing loneliness, especially among young people. Professor Yuying Tong emphasizes that the app invites reflection on single life, even though its tone is ironic. Despite the skepticism, the app reflects a profound reality of Chinese society, where more and more young people are facing loneliness and isolation.
