I need a coder, especially to develope an app.

My name is Shashwat Poddar and I am a student at Hansraj College, Delhi University. With the recent increasing number of rape cases in India, I feel we should create a space of help for those who need it. The app will be named 'Help' and can be downloaded. People can register on the app and state their address. The person in danger can trace the people nearest to her/him and can call for help.
