Woop-Woop! Realistic Police Siren!

Highly realistic 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 purchasesMakes your favourite US police car sounds: Wail (slow), Yelp (fast), Priority (super fast ) and Air Horn. 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. Thank you
