I worked on this app for UNICEF. We built a mobile website that tracks a user's activity and rewards them for going without their phone. Every minute users go without their phones helps provide clean drinking water to children in developing countries.

I was responsible for the UX of additional features added in the second year of running.

It was a 2015 Webby Award Winner
