Ever since I got my drivers license, I used the Blitzer.de App. Basically it's a smartphone application that warns you of speed traps. What's really smart about the app is that every driver can easily submit a speed which they saw.

Sadly the interface design of the app is a bit outdated and as a user I miss some features. So I decided to give the app a redesign based on their current looks and the features I'd like to see implemented. I started by wire-framing a new structure based on my experience with the app and the existing interface. I filled it in with an adapted version of the original corporate design and added a day- and night-mode for better usability in the car.
