Demumu's Web Launch Breaks Device Barrier for Viral Safety App

Demumu.co, the innovative personal safety application previously known as "Are You Dead?" or "sileme," has launched a major expansion by releasing a fully functional web platform. This move breaks the "device barrier," making the viral "anti-loneliness" safety tool accessible on any browser, regardless of operating system. The app, developed by Moonscape Technologies, addresses the "quiet anxiety" of modern solitary living by requiring users to check in every 48 hours; if they fail to do so, it automatically triggers emergency email alerts to designated contacts. Originally an iOS exclusive that climbed to become a top paid utility app in multiple countries, the platform now serves Android, Windows, Mac, and Linux users via Chrome, Safari, or Edge, responding to thousands of user requests for greater flexibility. The expansion was driven by the needs of digital nomads, writers, developers, and remote workers who spend their days on desktop computers and require a seamless cross-platform safety workflow.

The new web interface maintains the minimalist, "dead simple" aesthetic that made the mobile app a viral success, while optimizing for desktop environments with features like cross-platform sync, allowing users to check in on an iPhone in the morning and verify safety from a laptop browser at night. It also offers premium UI/UX, universal accessibility, and silent monitoring that runs discreetly in a browser tab during deep work sessions. The app's unique approach to personal safety has garnered significant media attention, having been featured in BBC, Wired, and Reuters, which highlighted its role in the "loneliness economy" and its explosive growth across Asia and the US. With over 100,000 downloads and a consistent 4.3-star rating, Demumu has proven that a simple "Are you okay?" can serve as a critical lifeline, providing peace of mind to users living alone.

Co-founder Mr. Guo emphasized that the web launch fulfills the company's mission to make safety tools platform-agnostic, ensuring that safety doesn't depend on which device one owns—whether on a phone in the subway or a laptop in a cafe. Early web testers, including freelance designers and remote developers, have praised the platform for streamlining their daily routines and offering a smooth experience comparable to the original iOS app. The Demumu Web Platform is live now at https://demumu.co, where existing users can log in to sync accounts and new users can sign up immediately without an app store download, with setup taking just 30 seconds. This expansion represents a significant step in bringing Chinese safety innovations to a global audience, reinforcing the vision that living alone shouldn't mean being invisible.
