Great new siren. Still clearly has a couple bugs that need fixing before it is on level with the simple siren. Would be nice if the slide switch worked. There is a bit of lag sometimes on the buttons but it sounds pretty close to a whelen siren. The only issue I really have with it is the tone difference between speakers and head phones. On the speaker it is almost flawless sound but when you put on headphones and use it there is clearly background noise like it was recorded in a moving vehicle on a highway. That's the only reason I give it 4 stars. Great app by all means and I'm sure they will fix the small bugs in future updates.

Easily one of the best. The only reason i give it 4 stars is because of some lag between switching sirens. Also I would recommend a longer time to hold the man button before it loops again. Other than that I would highly recommend it.

The sirens are great just wish they can take out some of the background noise in the siren but its fine but i mean when i turn off and on the sirens it has to load and i dont like that it takes away the realistic aspect

This app is pretty much exactly like their Simple Siren LMT app. The only difference is that the airhorn sounds like a firetruck. As soon as I opened the app, I regretted spending the .99 cents. I much prefer the police style airhorn and all the other sirens are the same. This is getting two stars because I was expecting a little different tones, and it's hardly different than the other.
