It would make for better nypd sounding sirens ### 4/5 — fun *2023-07-30, version 3.2.1* dis is fun. ### 5/5 — Good *2023-03-13, version 3.2.1* It’s is the best app I have ever had and It is so fun my kids love it!!! But for the wail make it so it go high then goes down slowly ### 5/5 — Honestly really high quality *2023-01-05* Look, I’m a siren geek alright? This is a smart siren, similar to the ones used by LAPD and NYPD, and other various departments. It is a great siren and a clever name. It works great on games with proximity chat and a microphone without noise suppression, for example DayZ(I will find others soon). It is great for Roleplay and other aspects, and for Christ sakes it is an amazing deal compared to a real one, but I wouldn’t recommend using this siren(or any siren real or fake) in real life unless you wanting a Police impersonation charge. However, 5/5. I do recommend remaking the Hi-lo to be a bit longer and even tones, which can be a bit different then the real one. I understand copyright and all that but it is worth a shot. The Next best thing for free would be SirenBox I guess. Used it for a bit but I prefer your apps honeslfy **Developer response:** Thank you so much! Glad you love it!! Yes unfortunately there are several aspects of these things that are copy written, so those elements are being avoided as to not create any issues. Will look into the hi-lo. Thanks again! ### 4/5 — Excellent app *2022-11-13, version 3.2.1* Now, if you could only do a scientific prototype / signals stat from NYPD of the 80s, that would be awesome! ### 5/5 — Add a rumbler *2022-04-15, version 3.2.1* Their app is great, the sirens sound just like a real police siren but please add a rumbler. ### 4/5 — Cool *2022-02-21, version 3.2.1* Cool ### 5/5 — A+…. Excellent *2021-11-28, version 3.2.1* Work perfectly every time in fact this is the best one in the market…. A+ ### 5/5 — Realistic *2021-11-13, version 3.2.1* Great App! Would love to see the option to run a duel siren and possibly try to add rumbler; even if you have to up the price ### 5/5 — Siren LMT *2021-10-01, version 3.2.1* This sirens are very great I enjoy listening to it I love the app the Los Angeles police department use this same sirens wail Yelp and man I love the app so much please put more apps simple siren LMT ### 5/5 — Amazing SS2000SM siren! *2021-09-03* My friend, this app is amazing! Can you tell me what program or software you used to create this app or how you created it? I’m interested in creating my own version if you don’t mind. ### 4/5 — Please update *2021-05-02, version 3.2.1* If this app gets the rumbler feature, I will give this app 5 stars. ### 5/5 — 没有更新。没有低频 *2021-05-01* 没有低频 差评 ### 5/5 — Consolidate/Simplify *2021-03-27, version 3.2.1* Neat App, worth the .99¢ Crystal clear through my PA. Although : (1) App name is way too long. Shouldn’t have [...] (2) Booting up time is long opening App (3) Surprise us with a couple Siren Mixes Otherwise I like it, 5 Stars. ### 4/5 — Review Regarding Rumbler Option Implementation *2021-02-24* Hello there reviewers of this sirenbox application! This siren application is almost complete. I would love it if you would add an update, specifically speaking to implement the “rumbler” option used in the New York Police Department. You know, I’m just saying. You don’t have to, but it would be more realistic if you could add that option by pressing “rumbler” just as the other buttons regularly. Thank you for reading this constructive criticism comment. Edition: Hello Jacob. I’ve noticed the description and it states that it’s copy-righted, but this was years ago. Even “OuttaMyWay!”’s multiple sirens application has the Rumbler tones in it. So, please, I’m just asking like all the others do, please implement this option. Thank you. **Developer response:** Hey there, after speaking with the company that owns the copyright, I am unable to keep it in. Sorry, believe me, I wish I could! ### 5/5 — 很好 *2021-02-02* 我想知道那两个man键和a/h键有什么用？ ### 5/5 — More sirens *2021-01-16, version 3.2.1* I like the sirens but I would like to see more like the CHP siren and the LVMPD siren ## Most critical reviews (10 lowest-rated) ### 1/5 — Simplesiren *2024-04-15* It’s fun you sound is not that great, I recommend EmergeNYC. There are more options for different sirens to choose and quality of sound is better you. **Developer response:** Hi Stu, sorry to hear that you do not like the app. There should not be any quality issues with the sound, but feel free to reach out if I can support. The other application does have more options, but does include copyrighted materials and comes at a very different price point, something I have wanted to keep low so more people can enjoy the app. ### 1/5 — Crappy sounds *2019-05-29, version 3.1* No HD sounds, just sounds like GTA 5 police sirens but with less reality ### 1/5 — No Sound *2019-01-07, version 3.1* Doesn’t work with my iPhone NO sound? ### 1/5 — Update it for IOS.11 *2017-12-25, version 2.5* Update ### 1/5 — Needs updating fast *2017-10-14* This is an amazing app but unfortunately because of the new update I cannot get the app if the creator is reading this PLEASE DO AN EMERGENCY UPDATE!!!! thank you The only reason why I rated 1 star is so I get the DEVELOPERS ATTENTION!!!! ### 1/5 — 开发者请你更新好吗 *2017-09-23* 系统更新完11了，你这个软件没更新，根本打不开，花了6块钱就这么解决？连用都用不了 ### 2/5 — 更新 *2017-11-07* 怎么还不支持iOS11 ### 3/5 — ADD RUMBLER *2024-03-17, version 3.2.1* Can u please add rumbler sirens in would be so much thank i will write a better review if u put rumbler ### 3/5 — Was a good app now it doesn’t play any sounds *2021-07-14, version 3.2.1* Had this app a year ago and was nice now it doesn’t play any sounds ### 3/5 — Pretty good *2015-07-29, version 2.5* Well, when you choose standby and change it just cuts whatever is off. It doesn't wind down which makes it not a good siren. I need you to fix this so people don't have to pay for something bad. ## Most praised reviews (10 highest-rated) ### 5/5 — The best option *2025-04-13* This app is really good. Everything works amazing and it is like an identical pathfinder!!!! For sure do recommend, it is worth it no doubt. ### 5/5 — A+ Excellent but… *2025-03-24* Work perfectly every time in fact this is the best one in the market…. A+ hand down but The only thing that it’s missing is the low frequency sirens just like WHelen Howler Or the federal signal rumbler.. Jacob if you see this please have your team work on this thank you ### 5/5 — Very good *2025-02-19, version 3.2.1* I love this app! It’s very cheap and realistic! It’s awesome and ye pretty cool! ### 5/5 — Amazing app + I have an idea for the futur *2024-07-16* The app is amazing and super duper realistic! I can now finally make realistic videos for youtube pretend responses! A thing you guys could try adding is an option to have dual sirens or rumbler which would make it even more realistic! Overall AMAZING app! ### 5/5 — Awesome app! *2024-04-22* The sirens sound amazing and are very high quality! I don’t know what else to say other than it being a siren app 😁 ### 5/5 — App *2024-01-18, version 3.2.1* Hello can you please get this same siren with rumbler when ever you can because I have a megaphone I wanna test it on my megaphone and my megaphone is with AUX ### 5/5 — Please download *2023-12-08, version 3.2.1* Absolutely amazing ### 5/5 — Great app *2023-11-22* Fantastic application, I was looking for one that matched my patrol vehicle at work for a DayZ RP (like mentioned in another review funny enough?) only issue is that the horn can’t play at the same time as other sounds. ### 5/5 — Worth the money *2023-09-14* This app is by far the best siren app I have ever used, sounds great and is very realistic. Definitely worth the money to buy. And my personal favourite of all the siren apps by this developer. ### 5/5 — Just like the real thing *2023-05-15, version 3.2.1* I’m a volunteer for the Sheriff and sounds are very good. Use it on my golf cart get some great reactions --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
