I don’t know what else to say other than it being a siren app 😁 ### 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. ### 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 ### 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. ## Frequently asked questions about Simple Sirens LMT ### What does Simple Sirens LMT do?
