Simple and lightweight Chrome extension that inspires positivity and productivity.Inspired by simplistic and beautiful new tab pages like Momentum and Embark, Serotonin is an extension that seeks to spread happiness through positive messages. Rather than incorporating a traditional clock, we built a countdown timer that reminds users how much time they have left to make their day amazing. At the end of the day, users have the option of submitting a short snippet about what made their day so great—-then waiting a few seconds to read about what made someone else's day incredible.
