I helped organize a weekend workathon called Improve Coimbra. The goal was to come up with concrete solutions for some of the city problems in just two days.
I teamed up with Tiago Serra to build UrbanFlow, a simple Android app and server to spot the city buses position. The goal is to crowdsource the data gathering, release more accurate timetables and distribute the data openly. If you live in Coimbra, give us an hand ;)
