'Are you Dead?': Chinese safety app for people living alone goes viral. How it works

The developers describe the app as a 'safety companion' aimed at people navigating solitary lifestyles.

A mobile application that requires users to regularly confirm that they are alive has emerged as the most downloaded paid app in China, drawing attention to growing concerns around isolation, safety and unnoticed deaths among people living alone.

The app, titled Are You Dead?, operates on a simple mechanism. Users are prompted to press a large on-screen button once every two days to confirm they are safe. If a check-in is missed, the app automatically sends an alert to a pre-selected emergency contact, warning that the user may be in distress.

Launched in May 2025 with little initial attention, the app has seen a sharp surge in downloads in recent weeks, particularly among younger residents living alone in major Chinese cities. Its rise has propelled it to the top of China’s paid app rankings at the beginning of 2026, according to multiple reports, including Dexerto.

The app’s popularity coincides with demographic projections indicating a sharp rise in single-person households. Chinese state media outlet Global Times has cited research suggesting that China could have as many as 200 million one-person households by 2030.

The developers describe the app as a “safety companion” aimed at people navigating solitary lifestyles, including office workers, students living away from home, and others who live alone by choice or circumstance.

Discussion around the app on Chinese social media platforms has been candid and emotionally charged. One user wrote: “People who live alone at any stage of their life need something like this, as do introverts, those with depression, the unemployed and others in vulnerable situations.”

Another comment reflected deeper anxieties: “There is a fear that people living alone might die unnoticed, with no one to call for help. I sometimes wonder, if I died alone, who would collect my body?”

Among those who have downloaded the app is Wilson Hou, a 38-year-old worker based in Beijing. Speaking to the BBC, Hou said he lives around 100 kilometres from his family and is currently separated from them due to work commitments. Although he returns home twice a week to see his wife and child, he said he often sleeps at his work site.

“I worry that if something happened to me, I could die alone in the place I rent and no one would know,” Hou said. “That’s why I downloaded the app and set my mum as my emergency contact.” He also noted that he installed the app soon after its release, concerned it might be removed because of its sombre name.

While the app has gained traction, its title has drawn criticism from some users, who argue that the wording is unsettling or carries negative connotations. Several have suggested alternative names such as “Are you OK?” or “How are you?” Others have expressed discomfort with the idea that registering for such a service could bring bad luck.

Moonscape Technologies, the company behind the app, has acknowledged the feedback. According to reports, the developers have said they are considering a possible rebranding in response to user concerns. Internationally, the app is listed under the name Demumu and has ranked among the top paid utility apps in several regions, including the United States, Singapore, Hong Kong, Australia and Spain, a trend believed to be driven in part by Chinese users living abroad.

The app costs 8 yuan, approximately Rs 103. It was initially released as a free service before transitioning to a paid model. The name itself is a wordplay in Mandarin, echoing the pronunciation of a popular food delivery app, Are You Hungry?, which helped it gain immediate recognition.

Little public information is available about the creators, though the founders have stated that the app was developed by three individuals born after 1995, working with a small team in Zhengzhou, Henan province. One of the founders, identified in Chinese media as Guo, said the app was developed at a cost of around 1,000 yuan. He later disclosed plans to raise funds by selling a 10 per cent stake in the company for one million yuan.

The developers have also indicated plans to expand their focus, including exploring a separate product aimed at elderly users. China has one of the world’s fastest-ageing populations, with more than one-fifth of its citizens aged 60 or above.

In a recent post, the company said: “We would like to call on more people to pay attention to the elderly who are living at home, to give them more care and understanding. They have dreams, strive to live, and deserve to be seen, respected and protected.”
