An indie app named si le ma (死了吗), translating to “Are You Dead Yet,” has rapidly gained traction in China. The app’s primary function is straightforward: users tap a button daily, and if they fail to do so for two consecutive days, it sends an email to a designated emergency contact, prompting them to check on the user.
The app’s creator, Guo, one of three Gen-Z developers, shifted from social and entertainment apps to this project, inspired by the deeper safety needs outlined in Maslow’s hierarchy. Guo stated, “That felt like a good direction,” emphasizing the app’s focus on fundamental human needs.
Rapid Adoption and Market Impact
In just a week, “Are You Dead Yet” became the top paid app in the Chinese version of the Apple App Store, also climbing international charts without any paid advertising. Guo noted that the app’s popularity surged after being featured by an influencer on RedNote, a prominent Chinese social platform.
Since its rise, the developers have been approached by over 60 investors, with discussions underway about funding. Some investors have reportedly offered millions of Chinese yuan for a stake in the parent company, Moonscape Technologies, which has launched only a few apps to date.
Pricing and User Demographics
Initially, the app was priced at 1 RMB (approximately 14 cents), but due to increased attention, the price was raised to 8 RMB ($1.15). Guo did not disclose the app’s revenue or user numbers but indicated that earnings would support long-term development.
The app has resonated particularly with individuals living alone, a demographic that has grown in China. According to a 2020 census, 25.4% of households were single-person, a significant increase from 14.5% a decade prior. This trend has led businesses to cater to the needs of solo dwellers, including companionship services.
Name Change and Future Plans
Recently, the developers announced a rebranding of the app to Demumu to better target the global market. This name change has met with resistance from fans who believe the original name contributed to its viral success. One popular comment on Weibo stated, “Baby, your previous name was the reason you went viral.”
The app was first launched in June 2025 and was initially free. Its simple interface features a large green button for daily check-ins. Guo mentioned plans to integrate artificial intelligence into the app, aiming to create a digital safety companion for users, although specific features were not detailed.
