Like I love it,

I love it, but my phone did get taken once

Why

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

Won’t take intruder pics.

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.

FAQ

What does the Security Alarm - AntiTheft app do?

This app acts as a security measure for your iPhone. It triggers an alarm and captures a selfie of anyone who attempts to touch or take your device without your permission. It aims to protect your phone privacy from unauthorized access.

What are the different protection modes available?

The app offers four strong protection modes: Motion, which alarms when the device is moved or taken; Power, which alarms when the power cable is unplugged; Headset, which alarms when the headset is unplugged; and Pocket, which alarms when the phone is removed from a pocket or bag.

Is this app free to use?

The application is free to download and use, but it does offer in-app purchases. These purchases likely unlock additional features or customization options beyond the basic functionality.

How does the app identify intruders?

When an unauthorized action is detected, the app captures a selfie of the person attempting to access your phone. It can capture multiple selfies from different angles, increasing the chance of identifying the intruder. These photos can then be shared.

Can the alarm be stopped easily?

Yes, the alarm can be stopped using TouchID or FaceID if your device supports it, or by entering a 4-digit PIN code. This ensures that only you can deactivate the alarm after it has been triggered.
