Quick Summary
A blunt question—"Are you dead?"—has become the driving force behind a viral app in China. The application, titled Si Le Me, requires users to press a button daily to confirm they are alive. If a user fails to check in for two consecutive days, the app alerts a designated emergency contact.
Designed specifically for the growing population of people living alone, Si Le Me has surged to become the most popular paid download on China's Apple App Store. The app costs 8 yuan, or approximately $1.15, to download. While the app was launched in mid-2025, its downloads spiked in early January 2026.
The app's stark functionality has triggered a wave of raw discussions on social media regarding isolation and the risks of solo living. Users on platforms like RedNote have interpreted the app's success as a collective "cry of loneliness," highlighting a societal shift toward atomized living.
The Rise of 'Si Le Me'
The app Si Le Me has quickly dominated the paid charts on the Apple App Store in China. The name is a literal translation of "are you dead" in Chinese. Its core function is simple: users must "check in" by pressing a button within the app. This mechanic is designed to ensure the safety of individuals living without roommates or family.
If a user goes silent for 48 hours, the app assumes a potential emergency and notifies a pre-selected contact. The concept grew out of online conversations regarding the safety and isolation of solo dwellers. The three co-creators of the app were all born in the mid-1990s. They launched the app in mid-2025, but it did not see significant traction until the first week of January 2026.
Despite its utility, the app's name has stirred controversy. Some social media users have referred to the title as inauspicious, comparing it to a curse. Despite these objections, many others have stated they are willing to pay the 8 yuan fee for the peace of mind it offers.

Solo Living Statistics
The popularity of Si Le Me mirrors a significant demographic shift in the country. Solo living is becoming increasingly common among both young city dwellers and the elderly population living independently. The app addresses the fears associated with this lifestyle change.
Projections published in 2021 by the Beike Research Institute, a real-estate research firm, estimate that China could have as many as 200 million one-person households by the year 2030. This would mean more than 30% of the population living alone.
Government data supports this trend. A survey conducted in 2021 revealed that nearly 60% of Chinese citizens aged 60 and above lived alone or only with a spouse. This figure represents an increase of approximately 10 percentage points compared to data from 2010.
Social Media Reactions
The sudden rise of Si Le Me has ignited a debate on Chinese social media. Users are analyzing what the app's popularity says about modern society. On RedNote, one user, Qian Wei, posted that they "sense a deep loneliness" behind the app's success.
Qian Wei elaborated on the changing social fabric, writing: "For much of China's history, kinship formed the basic unit of society, but 'this structure has completely collapsed' in the present day." They described the modern urban experience: "In big cities, everyone is an isolated, atomized individual. People live in soundproof apartments, not knowing the surname of their neighbors."
Another user, Huang Mu Xin Sheng, expressed feeling "extremely uneasy" about the app, arguing that it "reduces existence itself to a functional task." However, not all reactions were somber. Some users viewed the app as a form of "meme-style stress relief," a lighthearted way to cope with mounting pressure. One user framed the app as a source of certainty in an uncertain world, writing, "I check in, therefore I am."
"This creates an extremely intense fear, which is commonly known as 'lonely death.'"
