### 1/5 — This app

*2024-05-23, version 3.1*

I think this app is okay because first it does not have power call and Qb2

### 3/5 — Meh

*2023-07-22, version 3.1*

Pretty good app overall. Does what it’s supposed to. Don’t understand the point in paying the 2$ for the “full version” that doesn’t seem to add much. Also, it stops any other audio that is playing. Can’t play Spotify etc while using. Fix that and it would be great.

### 3/5 — Haha

*2023-01-17, version 3.1*

It’s hilarious to me that they want you to pay $2 to hit the horn

### 4/5 — Great game 1 suggestion tho

*2023-01-03, version 3.1*

So I like the game in general, it does what it was intended to do but I kinda wish that you could change the siren box to another type (like fire engine q2b pedals or something) but still it’s a great game I recommend it to anyone wanting an app sounding like a siren

### 1/5 — Can’t hear

*2022-09-23, version 3.1*

Can’t even hear the sirens

### 1/5 — Total trash

*2022-06-16, version 3.1*

Don’t buy it, I bought it for 2.79 USD and somehow got charged 11 CAD and the app doesn’t work. No noise at all. Absolute garbage from a garbage person.

### 3/5 — Ugh IOS broke it.

*2022-03-13, version 3.1*

Just discovered trying to test it out it’s broken. It doesn’t show openly but it will not make any sound at all now either through phone speaker or Bluetooth.

### 1/5 — terrible

*2022-01-29, version 3.1*

need to buy full version for lights and horn

### 5/5 — Make it more realistic

*2021-12-01, version 3.1*

Your phone flashlight should flash like real strobe likes on actual squad cars and the sounds should be more realistic

### 5/5 — Looks great

*2021-09-05, version 3.1*

It seems great from the reviews but for me it took a long time to download but that is ok
