Mininigma is a complete simulator of an Enigma Machine for your iPhone/iPad/iPod Touch.

As of version 4.0, Mininigma also includes a Custom Keyboard Extension (iOS 8.0 and newer), to use it from any app on your device, for instance, sending a mail, messaging, etc.

Basically, Enigma was a cipher machine used by the Germans during World War II for the encryption and decryption of secret messages. It looked like an old typewriter with some extra features.

Being fully compatible with the real Enigma means you can also use Mininigma to decode any of the original messages which can be found on Internet.

You can also generate a machine configuration based on a keyword or keyphrase. That means you'll only have to share that keyword to send a message!!

Mininigma can accurately simulate different types of machines: The Enigma I, M3 and M4, Railway, G-312, or Swiss-K, with some others coming in the future. You can read more about these, as always, on the Wikipedia :)

You can actually select between the different machine types and setup them as you would with a real one: choose rotors, configure them, or use a plugboard to switch letters. All at the tip of your finger.

Mininigma supports Copy/Paste to allow you to interact with any other application on your device. You can even copy/paste machine configurations in an encryptable string!!

Super APP decodes original enigma messages

Must Have App!

As soon as I saw this app I had to have it.

I know the history of the Enigma machines and thought it would be fun to try one out.

The app seems to be complete. After reading detailed descriptions of the real machines the app allows you to set everything there is to set.

To test it out properly I downloaded another Enigma emulator for my desktop machine. I set that up and this app in exactly the same way.(mixed up the rotors picked a reflector, added about 10 links in the plugboard and adjusted the rotor rings) I was grinning when my encrypted message was decoded flawlessly on the other app. That must prove that every bit of the Enigma has been replicated.

I am now ready to serve in the German Navy :)

This is obviously a labour-of-love app - my first impressions are that this is as close to a real enigma machine as you are likely to get in software! If you are at all interested in the machine please download and get a taste of what wartime encryption was like.
