App Tracks Vital Check-ins for Solo Dwellers

19 Jan 2026

The app 'Are You Dead?' for iPhone introduces a starkly simple way to handle check-ins, asking users to press a button every two days or alert a contact if they miss it.

App Features and Usage

The app requires users to tap a green button regularly. This action resets a reminder clock, and failure to tap triggers a notification to a designated contact. The app, named 'Demumu' internationally, gained traction among solo dwellers in urban centers, notably in China.

  • Name: Demumu (internationally)
  • Frequency: Every two days
  • Target: Solo urban dwellers
  • Market: Rising in China, 200 million projected solo households by 2030

Unlike advanced sensor apps, 'Are You Dead?' avoids complex setups, focusing on binary checks. However, it can produce false alarms if your phone dies or loses service.

Android Alternatives

Android users have similar check-in options. Google’s Personal Safety app offers a Safety Check timer, sending location alerts if the user doesn’t respond. Third-party apps like Snug Safety and Life360 provide scheduled reminders and alerts for missed check-ins, targeting families with additional features.

This system appeals in a time of increased solo living and safety concerns, with designs affecting user adherence. 'Are You Dead?' offers a direct prompt, while Android tools provide softer approaches with diverse features.

Whether through ‘Are You Dead?’ or comparable Android apps, these tools reflect growing trends in solo living and the importance of regular communication for safety.
