BACKGROUND ANDROID PROTECTION
Seconds can make a difference.
Guardião SOS looks for possible high falls and road accidents. It starts a warning countdown and, without a response, automatically sends a text with context and location.

HOW IT WORKS
What can start an SOS.
A short phone drop or jump is not enough. High falls require extended free fall, impact and post-impact verification.
Useful message
Likely incident type, estimated speed and a direct Google Maps link.
Local protection
Detection and SMS work without cloud. Only optional detector-improvement sharing is off by default.
CONTEXT
A simple screen. Sensors working underneath.
The app shows likely context, never a medical or forensic certainty.
CARGPS, activity, impact and deceleration
MOTORCYCLESpeed, dynamic lean, rotation and curves
SHORT DROPDiscarded; an isolated impact does not start SOS
HIGH FALLExtended free fall, impact and aftermath
DIRECT INSTALL
Install it and run the no-SMS test first.
Android may ask for permission to install apps from this browser. Open the app, set the SOS number and use “Test alarm without SMS” before enabling protection.
