Anti-theft alarm is a free Android app developed by RaLok Technologies under the Utilities & Tools category. This app makes your phone inoperable to the thief even after restarting the phone, changing the SIM card, or battery. The app is designed for people who are concerned about their phone's privacy and security. With the theft alarm, you can prevent your phone from being stolen, misplaced, or misused.

The app has several features that can be used in various situations. You can activate the charger mode to prevent theft while charging your phone. The motion mode helps to protect your phone from being accessed by someone else while you are away. The proximity mode can be used while traveling on public transport, which helps to protect your phone from being stolen from your pocket. Additionally, the app can also be used to prevent your friends, family, or kids from using your phone without your permission. The alarm will continue to ring until the right password is entered, making it impossible for the thief to turn off the alarm.
