Car Alarm is a free Android app developed by dragonn2 in the Utilities & Tools category.

The app is simple and easy to use, with a straightforward interface that includes a button to activate the alarm.

The app is fun to play with and can be used to prank friends or family members. However, it should be noted that the app is not a substitute for a real car alarm and should not be relied upon for security purposes. Overall, Car Alarm is a simple and entertaining app that can provide some amusement, but should not be taken too seriously.
