One tap, and the people nearby know

What happened

2nd place among 150+ participants at TechSparks (FCRIT).

Try it: one-tap SOS

Sample data

Press and hold the button (or press Enter). Everyone inside the circle hears about it.

  • 3 emergency contacts saved
  • 5 app users within 3 km
  • Nearest police station 900 m, hospital 1.4 km

Where it started

Existing SOS features call emergency services and stop there. We wanted to know what actually happens in the minutes that matter.

What we heard

From 14 interviews: asking for help takes too many steps when you're scared, and the people who could reach you fastest, the ones a few streets away, are never told.

What we built

One tap (or a shake) sends an SOS to emergency contacts and to app users nearby, with live location. A map shows nearby police stations and hospitals. Alerts update in real time over WebSockets, and a web portal lets police and hospitals see requests by category.

What happened

2nd place among 150+ participants at TechSparks (FCRIT).

What I'd do next

Design for false alarms from day one, and test how long the first alert takes to arrive on a weak 3G connection.
