Alarm is a self-defence/emergency alarm application with a rapid-movement and free-fall detector. You can also touch the screen to give a warning.

Not only a red screen blinking but also an alarm sound and a flash light are synchronized if the device has such functionalities.

The Apple Watch app also blinks but its limited for a few time only to save the battery.
