Mini209: M-209 cipher machine simulator app for iPhone and iPad

Mini209 is a complete simulator of an M-209 Machine for your iPhone/iPad/iPod Touch.

Basically, M-209 was a cipher machine used by the U.S. Navy during World War II for the encryption and decryption of secret messages. It looked like an old typewriter with no keyboard :) and some extra features.

Being fully compatible with the real M-209 means you can also use Mini209 to decode any of the original messages which can be found on Internet.


Mini209 supports Copy/Paste to allow you to interact with any other application on your device. You can even copy/paste machine key settings.
