The app - Himmat - is an initiative of Delhi Police. It will allow smartphone users to call the police control room and also trigger a 30-second audio and video recording at the press of the phone's power button.
Police said Himmat will help women contact police in the quickest possible time in an emergency.
A police official said though the app was developed keeping women in mind, it can be used by any smartphone user to contact police in the event of a crime.
The user will be asked to feed five emergency contact numbers of friends or relatives into the app's data base. When an SOS call is made, a message will be automatically sent to these five numbers.
"In this way, not only police, but the user's relatives and friends too will be able to come to her rescue," the official said.
The app is available as a free download via Google Play.
"User needs to register at Delhi Police website. After successful registration, user gets registration key (OTP) which needs to be entered to complete application configuration", the app listing notes.
"As soon as the user of Himmat app raises the SOS alert from the Himmat App, the location information and audio-video is transmitted to Delhi Police control room. Delhi Police can then immediately send the nearest Police help to the victim."
