This application may save your life someday.
(In the case of real emergency, I suggest you try other methods first. This application should be used as a last resort.)

You can display any text you like in the air.
It supports both English and Japanese , but some characters may be harder than the others to display.
Shorter text is preferable.

You can select an icon to display.

When turned on mirror mode, it displays text and icons inverted, so you can try and see it yourself on the mirror.

Try using this application in dark environment, and set screens brightness to the max setting.
Take a picture of what you displayed in the air using slower shutter speed.
