Sassy SOS

A discreet personal safety app disguised as a calculator. One trigger sends location, audio, and an alert to trusted contacts and partner NGOs — over data or SMS.

How to trigger SOS in the demo

  • ① Type 911 = on the calculator
  • ② Long-press the 0 key for 1.5s
  • ③ Tap the tiny Sis badge (top-right) 3 times

On a real device the trigger is also tied to power-button taps and a wake-word — kept silent here.
