Zerocrime empowers citizens to help prevent and eradicate crime. It is an online crowd-sourcing application that allows citizens to report and view criminal activity near them. Using this application, victims or witnesses to a crime can submit a short report by providing basic details such as location, date, time, type, and description of the event. Reporters are also asked to provide a piece of advice for fellow users. This crowd-sourced data is put on a map and users can scan areas near them to view criminal activity. In the future, users will also be able to identify high-risk zones through heat maps. Subscribers will get location-based safety alerts on their smartphones.
