Sister

A free personal safety app

83 % of women feel fear when walking alone at night* *Survey made by Sister
Why Sister? We, as women, would like to walk alone without fear at any time of day or night, but the street still doesn’t belong us. Many times we feel unprotected on the streets and use self-defense mechanisms such as dialing the police number, turning off the music on the phone or taking detours to get home. Sister is a geolocation application for women that aims to end the insecurity that we too often feel. We deeply believe that every woman has the right to move with total safety and freedom anywhere and at any time without feeling fear or worry. That is why we are committed to create an application that not only seeks to reduce the feeling of insecurity, but also prevents possible threats and responds in case of emergency.
Our mission Women, are brave and strong, but we don't want to show it continuously to safeguard our psychological and physical integrity. At Sister, we truly believe that there is a world in which men, women, boys and girls can live in harmony. And strength our skills from respect and love. That is why we seek to visibilize the violence and to invite all people to join together to eradicate it, from the deep love we feel for all human beings, of any gender, sexual orientation or race. Join Sister to turn things around and make this new world a little better.

How does Sister work?
Sister is a free app that tracks your location in real time with the best accuracy, so you can share it in real time to your trusted contacts. Sister comes with special features to increase women’s safety, such as a GPS that indicates you the safest route with the nearby police stations, a deterrent alarm to stop any kind of aggression, and a SOS mode to contact with the emergency services with just one click.
There are two main uses for Sister: prevention and emergency. The prevention mode shares the location of the user with their contacts in real time and has a GPS to display the safest route with the nearby police stations.
The emergency mode has a SOS button to send the location to the trusted contacts warning them that the woman is in danger. It also displays the phone number of the emergency services.
Sister is free and available to download worldwide for Android and iOS smartphones.
