Critical Maps is an open source Android and iOS App to organise the monthly Critical Mass cycling event around the world.

It's a small app with one purpose – to see where other app users are. It helps to see where the cyclists are heading and help people to join later. Also it provides an anonymous chat for sharing important information during the ride and a small guide with rules to keep the ride save and fun for everybody. I redesigned both apps, made a new logo and build the website.
