Designing Emergency-Ready Apps: Building and Open-Sourcing an SOS System

Many safety applications fail during real emergency situations, not because of lack of features, but because they are not designed for panic scenarios.

In this talk, I will walk through my journey of building a women safety mobile application focused on instant response and minimal interaction. The session will cover how I approached designing an SOS system that works reliably under stress, key product decisions, and the challenges faced while building the MVP.

I will also share how I am open-sourcing core components of the system, including reusable SOS logic and emergency contact handling, so that other developers can build safety-focused applications more effectively.

This talk connects real-world problem solving with open-source contribution, showing how individual projects can evolve into reusable tools for the broader community.

• Why most emergency/safety apps fail in real-world panic situations

• How to design low-friction, instant-response user flows

• Technical breakdown of an SOS system (trigger, contacts, alerts)
