Highlights
  • Enigma machine simulation
  • Message encryption and decryption
  • Keyword-based configuration generation
  • Multiple Enigma machine types supported
  • Rotor and plugboard configuration
  • Copy/Paste support

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

Verdict

The call

The clearest difference is price: Physics Toolbox Sensor Suite at Free against Mininigma's $1.99. Physics Toolbox Sensor Suite also leads on update cadence (weekly vs every 6 months) and ratings volume (1.8K vs 30). Mininigma's advantage is in-app purchases (none vs 1) and review sentiment (91% vs 81%). On rating, ads, device support and iOS requirement there is nothing between them.
