Antitheft – Intelligent Protection System for Android

Turn your phone into an anti-theft device

Antitheft is a complete smart security system for Android devices, designed to protect your phone against theft, unauthorized access, and intrusions. With automatic actions, a modern interface, and full integration with device administrator permissions, the app works silently in the background to detect suspicious unlock attempts and respond with powerful actions such as photo capture, email alerts, and alarm activation.

You’ll be able to identify who tried to access your phone, receive the intruder’s photo along with GPS location via email, and even remotely wipe all data in case of theft.

Perfect for both end-users and developers looking for a clean, fully functional and well-documented protection system.
