In this fast changing era and smart world, the citizen safety is not being on point till date. Due to lack of proper actions in emergency situations, people are facing life threatening situations, so we are trying to contribute little effort towards the citizen safety. We developed an application named “Android Application for Citizen Safety”, which is helpful in emergency situation. When a person is in any emergency situation just by shaking their mobile for 4 times, this application will send an emergency message for emergency contacts which are previously saved in the application. This mobile application is very much helpful for anyone. This application will help the user to send the SMS and current location through GPS.
