Abstract - Women’s safety has become one of the most critical social challenges in recent years due to the increasing number of harassment and crime cases. Immediate response during emergency situations isoftendelayed duetopanic, lack of communication, or unavailability of support systems. This research paper presents the design and implementation of a Women Safety Mobile Application developed using the Flutter framework. The proposed system provides a one-touch SOS emergency feature that instantly shares the user’s real-time GPS location with registered contacts and nearby authorities
The application integrates Firebase Authentication forsecure login, Firestore for real-time database management, and Firebase Storage for storing recorded multimedia evidence. Upon SOS activation, the system sends SMS alerts, initiates emergency calls, starts automatic video recording, and uploads data to the cloud server. The system also supports offline SMS alerts when internet connectivity is unavailable.
The primary objective of this application is to reduce emergency response time, provide secure evidence collection, and enhance personal safety through smart mobile technology. The application is lightweight, user-friendly, and optimized for Android devices. Experimentalresultsshowthat the system responds within 2–3 seconds under stable network conditions, making it an efficient and reliable safety solution.

1. INTRODUCTION
The rising crime rate against women has necessitated the integration of technology into personal safety measures. Traditionalmethodsofseekinghelpoftenfailduetopanicor lack of time. To address this, we propose a robust mobile application developed using Flutter framework, ensuring cross-platform compatibility (Android). The application bridges the gap between the victim and emergency responders by automating the alert process. Unlike conventional applications that rely solely on SMS, this systemintegratescloud-baseddatastorage,real-timemap visualization,andmultimediaevidencerecordingtoprovide aholisticsafetysolution.
2. OBJECTIVE
The main objectives of the proposed system are:
1.ToprovideinstantSOSalertfunctionality.
2.Tosharereal-timeGPSlocationwithemergencycontacts
3.Toenableautomaticcallingtopolicehelplinenumbers.
4.Torecordaudio/videoevidenceautomatically.
5.Todesignasecureanduser-friendlymobileapplication.
3. PROBLEM STATEMENT
Despite the availability of helpline numbers and safety applications, many women fail to receive immediate assistanceduringdistresssituations.Existingsystemslack integrated real-time tracking, automatic multimedia recording, and offline alert support. Therefore, there is a needforareliablemobile-basedsafetysystemthatensures instant communication, accurate location tracking, and securesevidencestorage.

• SMS-Based Systems: Manyexistingappssendsimpletext messages.However,theylackreal-timetrackingupdatesif thevictimkeepsmoving.
• GPS Trackers: Hardware-basedtrackersareeffectivebut requiremaintenanceandcharging.
The proposed system overcomes these limitations by integrating dynamic GPS tracking with a user-friendly software interface, eliminating the need for external hardware while ensuring high accuracy through mobile sensors.
5. SYSTEM ARCHITECTURE
The system architecture is designed to be modular and scalable. It operates on a client-server model where the mobileapplicationactsastheclientandFirebaseservesas thebackend.

ThedevelopmentmethodologyfollowsanAgileapproach, allowing for iterative testing of the SOS features. The executionflowisasfollows:
• User Initialization: Theusergrantsnecessarypermissions (Location,SMS,andCamera)uponfirstinstall.
• Contact Configuration: Theuserdefinesaprioritylistof emergencycontacts(Family,Police).
• Emergency State: WhentheSOSbuttonistapped,theapp enters ’Distress Mode’. Background services are killed to prioritizethelocationthread.
• Data Transmission: Encryptedlocationpacketsaresent to the cloud database, which updates the observer clients (registeredcontacts)inreal-time
