Too simple and bad menu. Only one decent siren sound, many useless functions and it takes to much time to change between those sounds, plus you don't know which is which like in almost all similar apps.
Works Works wonders against neighbors dog barking at my house non stop all I have to do is plug this into my speakers and point at their house within 5 min they finally let their dog in.
Do not work No alert on shake its a false 911 app
Good for videos One of my favorites
Not too bad
Sirens have been added optional features.
