3. Introduction
 The women safety is the prime concern in today’s world considering the jump in the
number of incidents and crime rates against women, especially in the metro cities where
women have to stay out for long.
 According to a research report of Bangladesh police and Investigation Agency which
was conducted in 2020, around 85 percent of the women had faced some or the other
kind of harassment before moving out of the teenage.
 As women need to travel late night sometimes, it is important to stay alert and safe.
Although the government is taking necessary measures for their safety, still, there are
free safety apps for women that can help them to stay safe.
 Most of the females nowadays carry their smartphone with themselves, so it is
necessary to have at least one the below-mentioned personal safety apps installed.
Such a safety app for girls can certainly help in some way or the other.

4. Proposed System
 The basic aim of the system is to develop a low cost solution for GPS based
women tracking system which can be applied to various domains of the
industrial and personal use just by using the very common mean i.e. mobile
with android enabled.
 The main objective of the system is to track the person which has an
android enabled mobile by extracting the longitude and latitude of that
target person.
 The primary objective of our system is to track the person and plot of the
location on real time system like Google map.

Each time a user makes a phone call, an
emergency signal will be generated automatically
and then an information alert will be sent to the
contacts that have been added to the emergency
call.
 low-battery alarm: when the user’s battery will be
less than 10%, a low battery alert message will be
sent to the emergency contacts.
 It consists of a GPS device, an Android phone.
The unit will provide status information such as
latitude, the longitude of the user.
