The app "Sileme," which translates to "are you dead," has been removed from both Apple and Android app stores, confirmed by a search conducted by the Global Times. Following its delisting, similar apps have emerged, such as "Alive Yet? - Dead Yet? SMS Version" and "Dead Yet? Drift Version." One of Sileme's founders, surnamed Guo, confirmed its removal. Sileme's official Weibo account announced a daily check-in feature and invited the public to suggest a new Chinese name, while also revealing plans to adopt the global brand name "Demumu" in the next version. The app is designed as a safety tool for individuals living alone, allowing users to check in daily, with alerts sent to emergency contacts if they fail to do so within a set timeframe.
