With Whistling Lights you can be aware of the red light cameras near you!
When you use the app and start monitoring the distance to red light cameras you will be notified by a unique whistling sound that tells you when you come within 150 Meters of a light. Since the app does not use your standard notification sound you will never get tempted to look at your phone while driving.
Whistling Lights comes with a widget that you can place on your homescreen or lockscreen to turn on or off the distance monitoring without having to open the app.
