SentryOne: Emergency SOS Alert

JATIN KUMAR

About this app

SentryOne is a personal emergency SOS safety app designed to protect
you during critical and dangerous situations.

CORE FEATURE — SOS ALERT
With a single tap, SentryOne sends an emergency SMS containing your
real-time GPS location to all your saved emergency contacts. This
works even without internet using direct SMS.

EMERGENCY CONTACTS
Easily search and add emergency contacts directly from your phone
contacts. Your contacts receive your live location the moment you
trigger SOS.

FLASH SOS SIGNAL
SentryOne uses your device camera flash to emit a rapid blinking
distress signal to attract attention in dark or dangerous environments.
No photos or videos are ever taken.

LOCATION SHARING
Precise GPS location is captured and shared via SMS when SOS is
triggered. Background location access ensures accurate coordinates
are available even when your screen is off during an emergency.

VIBRATION ALERT
Device vibrates to confirm your SOS has been sent successfully.

WHO IS IT FOR
Anyone who values personal safety — solo travellers, women, elderly
users, and anyone who wants a reliable emergency alert system.
