pressing power button the app or shaking the phone will send alert to nearest ambulance driver which is available
among registered users also send message to emergency contact number. This helps to find appropriate hospital for his
emergency even in an unknown area. This app also provides facilities to store electronic healthcare data which can be
accessed by hospitals. It is observed that people in unknown area are in severe danger if they didn't able to find hospital
quickly. In emergency case a single minute counts. So it is very important that automatic applications must be used for
decision making, Maintain up to date status of the hospital and saving the time which can save life of the patient. The
proposed system locates nearest available hospital, contacts its ambulance emergency system, accesses a Electronic
Health Record of emergency patient that can critically assist in pre-hospital treatments. The system will identify
