Morse-it

Morse-It is an easy to use application that allows to translate, interpret, type, learn, convert Morse code, and much more.

It is retina display enhanced, universal binary (run on iPhone/iPod and iPad), and is compatible with VoiceOver. 

Type some text and it will be automatically encoded into some fullscreen flashing effect of the associated Morse code. 
The flash light of your device will also be used. 

Your “SOS“ messages will be seen quite far away !
