Personal Emergency Alarm app for iPhone and iPad

You can now have your own pocket alarm,
like Sheldon Cooper alarm.

It allows you to quickly and easily call attention to yourself in case of an emergency or in some other loud environment.

Because of its simple interface, activating the alarm does not require precise movements or even looking at the screen. This is essential in case you are in a situation where either your movements or your field of vision are restricted.

Also, you can configure the text displayed and the alarm sound of this app, in order to more precisely broadcast your current situation/status as need.
