Stay Safe Security App with Scream and SOS Features

Introduction

In an age where personal safety is a growing concern in public spaces like train stations, footpaths, and bus stands, GuardianScream emerges as a reliable safe security app for everyone—women, men, and senior citizens.

Technical Framework

Powered by Google’s Dart programming language and SQLite for back-end data management, the app is built on the cross-platform Flutter framework. Android Studio serves as the official IDE for crafting this efficient and user-friendly app.

Key Features

• Scream Alarms: Choose between male or female screams or police sirens as your alert sound. In times of danger, the alarm screams will go off, attracting attention and possibly deterring attackers.
• Fake Call Function: Generate a fake call that lasts a minute to divert attention. The call will display the caller’s name and number.
• Location Sharing: Easily share your live location via a web link with family members and friends who can then track you on Google Maps.
• Quick Access List: A list of contacts is displayed in the app for immediate access during emergencies.
• SOS Shake Feature: In dire situations, shake your mobile phone five times to send an email or SMS to your emergency contacts, complete with a location link.

Advantages

• Easy to maintain and extremely user-friendly
• An effective tool for self-defense, particularly for lone travelers
• SOS and location-sharing features enable quick communication with family and friends
• Scream alarms are a great way to deter attackers and attract attention
