SOS

The SOS app is an app that makes it easy to use the alarm buzzer.

This is useful when you want to ask for help, or when you want to ask for help but cannot speak.

When you press the SOS button, the alarm buzzer sounds and the flashlight turns on.

In addition, you can easily make a call to the registered phone number by simply pressing the phone button.

It can be used for walking alone at night or for self-defense in an emergency.
