• Realistic police siren sounds
• Flashing lights
• Doppler effect (shake your device to simulate the change in tone that you hear when driving past at speed)
• Fun tactile interface
• NO ads, NO in-app purchases

Makes your favourite British police car sounds:
• Wail (slow)
• Yelp (fast)
• Pulsar (super fast!)
• Hi-lo (two-tone)
• Air Horn

We used signal processing to convert real-life siren recordings into synthesised sounds. This results in uniquely pure and loud audio that closely reproduces the sounds of a real siren. We chose the Premier Hazard siren which equips most UK police vehicles.

For extra fun, turn on a fast siren or hold the horn and shake the device to simulate the tone shift that that you would hear if the police car sped past you and drove away. This is called the doppler effect.

You just can't help tap those buttons!

Warning: features mild strobe light effects.
