• 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 purchases

Makes 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. This is called the doppler effect.

I first made this app for my little one's enjoyment. He deserves high-quality toys, and so do you! So I went the extra mile, reverse-engineered real police siren recordings to synthesise pure, loud, true-to-life sounds, and packaged the result in a fun touch-sensitive app.

You just can't help tap those buttons! Even more noisy fun when you play it together with your friends!

Warning: features mild strobe light effects.

Great but needs work....

I don't know if you guys think so too but should the panel be bigger and have more realistic options? Like for instance, it should have an option like on the real siren systems where you can "program" the siren sounds to a specific name or number like if Manual was originally Wail like it is now, you can change it to the "Warble" tone, (basically Whelen's version of a PowerCall), I would love that. And some other options... Also, fix the horn!! If you hit it rapidly after like the 7th hit on the button the sound will sound different and I H A T E that. Overall, great app... Just USE THESE IDEAS!! I am sure people would love these ideas as much as I do.



I love this app 5 stars
