Demumu App Rebranding 2026: Viral 'Are You Dead?' Safety Tool Goes Global

The app that asks the question everyone's thinking but no one's saying is going global. Sileme, the viral Chinese safety tool that literally translates to "Are you dead?", has officially rebranded to Demumu for its international debut.

The Demumu App Rebranding 2026 Strategy

According to Reuters and Al Jazeera, the team behind the hit safety tool announced on Weibo this Tuesday that they'll adopt the name 'Demumu' for their upcoming global version. The move follows a massive surge in popularity that saw the app reach No. 1 on Apple's paid app chart this week.

To support its growing infrastructure, the company introduced an 8-yuan ($1.15) subscription fee last Sunday. On the international App Store, users are already seeing charges of 8 Hong Kong dollars ($1.03) for downloads, marking a clear shift toward a sustainable monetization model.

Solo Living and the Rise of Safety-as-a-Service

The app's premise is straightforward: it's a lightweight tool for those living alone. Users set an emergency contact and must check in daily; if they fail to do so for consecutive days, the app automatically notifies their designated contact. With China's solo living rate exceeding 30% and an estimated 200 million one-person households, the demand is undeniable.
