In China, a one-tap app lets you check in with your 'home alone' friends
The Si Le Me mobile app, whose name translates to “Are you dead?”, prompts users to check in daily and automatically alerts an emergency contact if no activity is detected for two consecutive days, a feature that has fueled its surge in popularity across China.

A bluntly named mobile app asking users a single, unsettling question — “Are you dead?” — has unexpectedly climbed to the top of China’s paid app charts, igniting a wider conversation about loneliness, safety, and modern urban life.
Called “Si Le Me,” a literal translation of its provocative prompt, the app requires users to tap a daily check-in button. If no activity is recorded for two consecutive days, an emergency contact is automatically alerted. Designed primarily for people living alone, the app costs 8 yuan (about $1.15) and has become the most downloaded paid app on China’s Apple App Store this week.
Although launched in mid-2025, downloads surged only in early January, according to Chinese media, fueled largely by social media attention. Its stark name, jarring even by app-store standards, has struck a nerve online, where users have linked its popularity to growing isolation in Chinese cities.
Living alone is increasingly common in China, particularly among young professionals and the elderly. Projections from the Beike Research Institute estimate that by 2030, China could have as many as 200 million one-person households. A government survey conducted in 2021 found that nearly 60 percent of people aged 60 and above lived alone or only with a spouse, a sharp increase from a decade earlier.
One of the app’s creators told local media that the idea emerged from online discussions about personal safety and the fear of being unnoticed in emergencies. The three co-founders, all born in the mid-1990s, said they wanted to create a simple but practical solution.
Online reaction has been swift and emotionally charged. On RedNote, users described the app as a reflection of deep societal loneliness. One commenter wrote that urban life has reduced people to “isolated individuals in soundproof apartments,” feeding anxieties about dying alone.
Others criticized the app’s name as unsettling or inauspicious, urging developers to rebrand. Still, many said they were willing to pay for the reassurance it offers. Some users approached it with irony, framing the app as dark humor or “meme-style stress relief” in an increasingly uncertain world.
As one post summed it up succinctly: “I check in, therefore I am.”
