‘Are You Dead?’ Safety App for People Living Alone Goes Viral In China

Living alone gives people independence, but it can also raise small, everyday concerns like what happens if no one hears from you for a while. As more people choose to live on their own, these concerns are becoming part of daily conversations. That’s where a new app in China has quietly stepped in and sparked widespread attention.
 

TL;DR

 

• Sileme, a Chinese safety app for people living alone, has gone viral online.
• Named after the phrase “Are you dead?”, the app is being rebranded as Demumu for a global launch.

Living alone is becoming more common in China, and a new app built around this reality has quickly gone viral. The app is called Sileme in Chinese, a phrase that translates to “Are you dead?,” and is now being rebranded as Demumu for global users. It is designed as a simple safety check for people who live by themselves.

The idea is straightforward. Users set up one emergency contact and are expected to check in on the app regularly. If they fail to do so for consecutive days, the app automatically sends a notification to the chosen contact. The development team describes it as “a lightweight safety tool created for solo dwellers,” whether they are students, office workers, or anyone who has chosen a solitary lifestyle.

The app’s popularity increased, triggering a discussion across Chinese social media platforms like Weibo. Its timing shows a broader social shift: China may now have up to 200 million one-person households, with more than 30% of people living alone, according to state newspaper Global Times.

As downloads spiked, the company announced changes. On Sunday, Sileme introduced an eight yuan ($1.15) subscription fee to help cover rising costs. On Apple’s App Store, the app which is already listed under the name Demumu, climbed to number two on the paid app chart after briefly topping the list. The price there currently stands at HK$8.

The team also revealed plans to rebrand globally. “Thanks to all netizens for their enthusiastic support. We were originally just an unknown small team, co-founded and operated independently by three born after 1995,” Sileme said.

The name change, however, has mixed reactions. Some users urged the company to keep the original title, while others suggested alternatives like “Are you alive,” “Are you online,” or “Are you there.” One user commented, “Maybe some conservative people can't accept it,” but added that the app serves a real safety need and “will make us unmarried people feel more at ease to spend our lives.”

For many, the app’s direct name may feel uncomfortable, but its purpose has clearly connected with people. As more people live alone, the app’s popularity shows a growing need for simple ways to feel safe and connected, even in a solo life.
