The personal safety application Demumu, also known as "Are You Dead?" or "sileme," has expanded from an iOS-exclusive platform to a fully functional web platform accessible on any browser. This expansion addresses a critical gap identified through user feedback: the need for safety verification during work hours when users are primarily on desktop computers rather than mobile devices.
Originally launching as an iOS exclusive, Demumu quickly became a top paid utility app in multiple countries, designed to notify a user's contacts if they fail to check in regularly. The company received thousands of messages from users who appreciated the iOS experience but required more flexibility. The new web interface at https://demumu.co maintains the minimalist aesthetic of the mobile app while optimizing for desktop environments with features like cross-platform sync, allowing users to check in from different devices throughout the day.
The web platform's key features include universal accessibility for Android, Windows, Mac, and Linux users via browsers like Chrome, Safari, or Edge; automatic emergency alerts that trigger email notifications to designated contacts after missed consecutive check-ins; and silent monitoring that runs discreetly in a browser tab during work sessions. This expansion ensures that safety tools are accessible regardless of operating system, addressing what the company calls the "device barrier" that previously limited access.
Demumu's approach to personal safety—requiring users to check in every 48 hours or trigger emergency alerts—has gained significant recognition for addressing the "quiet anxiety" of modern solitary living. The app has been featured in major news outlets including Wired, which explored the cultural impact of the app's blunt approach to mortality in their feature "China's 'Are You Dead Yet?' App," and Reuters, which highlighted the explosive growth in "Viral App for Single Living Goes Global." BBC News also discussed the app's role in the "loneliness economy" and the peace of mind it provides to users.
With over 100,000 downloads and a consistent 4.3-star rating, Demumu has demonstrated that simple safety verification can serve as a lifeline for those living alone. The expansion to web platforms particularly benefits digital nomads, remote workers, writers, and developers who spend significant time on desktop computers. Early web testers have reported that the ability to check in from a laptop without picking up a phone has streamlined their workflow and made safety verification a natural part of their daily routine.
The company's vision emphasizes that safety should be platform-agnostic, whether users are on phones in transit or laptops in cafes. By removing hardware friction, Demumu aims to make safety tools universally accessible while maintaining the privacy-focused, automated check-in system that has made it a cultural phenomenon. The web platform is now live, allowing existing users to sync their accounts and new users to sign up without app store downloads, representing a significant step toward universal safety accessibility.
