Slow Down is a free app in the App Store created by the European road safety organisation OVK (Parents of Children Killed in Road Accidents), which will prevent you from getting speeding tickets and is designed to raise awareness on carelessness while driving. The movie above explains how the app works.

Warning: The Slow Down App uses GPS to work out your current driving speed. Continued use of GPS running in the background can dramatically decrease battery life.

You can download the Slow Down app for free in the App Store.
