China's Leading App Tests Your Vitality Daily

Currently trending is an app with a singular feature. Aptly named 'Are You Dead Yet' (死了吗), the app requires users to press a button each day. Missing to do this for two consecutive days prompts an automatic email to an emergency contact, advising them to physically check on the user.

Guo, one of the trio behind the app, has a history of creating social and entertainment applications. Seeking a new direction, he was inspired by Maslow’s Hierarchy of Needs, recognizing the wide appeal of addressing safety. Guo told WIRED about his shift towards this broader need.

This mix of practicality and humor resonated with Chinese youth, catapulting the app to the top of the Chinese App Store. Remarkably, its popularity surged without any advertising, climbing global charts as well. Guo notes the lack of funds for promotion.

Over 60 investors reached out after the app's viral rise, sparking financial discussions. Offers already include millions in yuan, with upcoming announcements expected. Guo expresses surprise at the overwhelming response and investor interest.

Initially offered for 1 RMB ($0.14), the price rose to 8 RMB ($1.15) amidst growing interest. Despite being non-subscription, Guo withheld specific earnings and user figures, emphasizing plans to reinvest for app development.

The app succeeds notably with individuals living alone. With the rise in single-person households in China, businesses increasingly cater to this demographic through virtual and physical companionship.

The app’s name will officially change to 'Demumu' for a wider global appeal, a nod to Labubu’s naming structure. Despite user affinity for the original name, the developers aim for broader market reach.

Fans resisted the change, loving the humor and directness of 'Are You Dead Yet.' On Chinese media like Weibo, sentiments highlight the original name as key to its viral success.

Launched as a free app in 2025, its interface hosts a blank backdrop with a singular large green button, requiring a daily tap to log existence. Creating the app cost a mere two hundred dollars, with its name humorously riffing on Alibaba's food service app.

Early traction was minimal until picked by an influencer, propelling it to number one among China’s paid app rankings. According to Sensor Tower, the app rose to prominence in January 2026.

Future innovations include integrating AI for enhanced safety monitoring, though specifics remain sparse. Guo envisions an AI assistant capable of providing robust support through the app.
