Girls learn app coding to navigate a way out of their Mumbai slum

With apps to reduce queues for water and to protect women in danger, a project teaching computer skills to girls in India's Dharavi slum is changing aspirations

Ansuja Madival's mother, who works as a maid, had never touched a tablet before, so the 15-year-old had to show her which buttons to press. "She was so happy when she saw what I had made," Ansuja says. "She never knew I was so good at computers."

No one thought schoolgirls from Mumbai's Dharavi slum could code mobile apps. The girls didn't even know what an app was until recently.
