### 4/5 — Security system

*2026-08-21, version 2.0.2*

It’s the Best alarm system for iPhones,it scares away any intruders if touched and the alarm is loud! 😜😁🤣 I have it on all my iPhones.

### 5/5 — Like I love it,

*2026-03-21, version 1.0*

I love it, but my phone did get taken once

### 1/5 — Why

*2026-02-08, version 1.0*

Terrible why would you even make this app if most of it is paid and it has annoying ads in the middle of the alarm

### 1/5 — Won’t take intruder pics.

*2025-11-26, version 1.0*

It might do other things but it won’t take pics of an intruder trying to access your phone. That’s all I’m interested in.

### 3/5 — Nice

*2025-11-15, version 1.0*

Good

### 1/5 — It doesn’t work

*2024-12-26, version 1.0*

One

### 1/5 — Rubbish app

*2024-08-20, version 1.0*

With great expectations I purchased the Premium version of this app, but so far it’s proven totally disappointing… When the alarm has been set, it has never taken any pictures to identify the intruder, and when the alarm went off, despite initiating the fingerprint access option, it was an absolute nightmare to turn off… Currently, it has ceased operating completely…
I would very much appreciate my money back, but sadly, I believe that might prove to be a vain and unattainable hope…
It is not fit for purpose, and quite frankly feels nothing short of a scam…

### 5/5 — It’s a good app

*2024-05-23, version 1.0*

A really good app and the beep so loud I’m gonna test it to see if someone grab my phone

### 1/5 — Muy mala

*2024-03-25, version 1.0*

No toma foto a intrusos que intentan desbloquear el teléfono es una total estafa no sirve para nada más que sacarte 6 dólares no la descarguen no sirve

### 5/5 — Best

*2024-03-17, version 1.0*

It is the best
