Turn your iPhone into an authentic WWII Enigma machine. Send encrypted iMessages that only recipients with matching settings can decode — just like the real thing. Make your cipher unbreakable by defining your own custom rotors and reflectors, eliminating the historical Enigma's notorious no-self-encrypt weakness. Cipher any language in any app with the Enigma Keyboard and Share Extension. HOW IT WORKS The Enigma cipher routes each keypress through a cascade of rotors and a reflector, substituting letters in a way that advances with every press. The simulated historical machine uses different rotor types, reflector types, positions, ring settings, and plugboard pairs — producing ciphered text exactly as it was done in history. The app also revitalises the historical machine by letting you define custom rotors and reflectors. Custom reflectors can include fixed points, eliminating the no-self-encrypt weakness. The expanded code space reaches 26! × 26! × 26! — approximately 10^78 — making messages virtually unbreakable. Enigma Cipher also supports all world languages, and lets you cipher and decipher in any iPhone app via the Enigma iMessage Extension, Enigma Keyboard, and Enigma Share Extension. FEATURES · iMessage Extension — compose and send encrypted bubbles directly in Messages; tap a received bubble to decrypt · Custom Keyboard — type encrypted text in any app, with a compose area showing plaintext and ciphertext side by side · Share Extension — highlight any text in any app and decrypt or encrypt it instantly · 5 historical rotors (I–V), 3 reflectors (UKW-A/B/C), and a 10-pair plugboard · Design your own custom rotors and reflectors with a visual wiring editor and randomizer; add fixed points to your reflector to eliminate no-self-encrypt · Share Enigma settings with another iPhone via QR code display and scan · Codebook — save, load, and share machine configurations · Signal path animation — watch each keypress travel through rotors, reflector, and back · Brass and mahogany UI inspired by the original hardware · Sound effects · Fully offline — no account, no server, no data collection THE MACHINE The container app is your settings and codebook control centre. A gear dial row at the top shows rotor positions in real time. Change rotors and rewire plugboard cables with a realistic interactive UI. The tester lets you encrypt and decrypt on a lampboard-style keyboard, with paper tape strips for input and output. All settings — rotor choices, ring settings, reflector, plugboard, and initial positions — are shared across the Enigma Keyboard, iMessage Extension, and Share Extension. SHARING SETTINGS Export your machine configuration as a QR code to share with a friend. Both devices must use identical settings to exchange readable messages — exactly how Enigma operators coordinated in the field. PRIVACY Enigma Cipher is fully offline.

Turn the rotors, plug in the cables, press a key and watch which lamp lights up. Enigma brings history's most famous cipher machine to your iPhone and iPad, so accurately that the app decrypts surviving radio messages letter by letter. Please note: the app is in German. A MACHINE YOU CAN TOUCH • Seven models to operate yourself: Enigma D, K, G, I, M3, M4 and T • Rotors in 3D, turned with your finger, with a settable reflector on the commercial models • A plugboard you can tap: plug in the cables like on the original • Lampboard and keyboard, input and output in groups as sent by radio • The Enigma M4 from the Deutsches Museum as a 3D scan you can rotate TWELVE MODELS FROM 1923 TO 1945 From the printing "Handelsmaschine" to the U-boat Enigma M4: every model has a profile with a drawing, historical photos where freely available, dimensions and weight where documented, rotors, key space, codebreaking and history, plus fun facts with sources. LEARN WITHOUT PRIOR KNOWLEDGE • "What's what?" tour: learn where everything is in one minute • Free step-by-step demo on the Enigma I • How operators typed without a space bar, digits or punctuation, with a try-it field • All models compared: how secure were they, and when were they broken? • Technical terms explained in plain language ENIGMA PRO (ONE-TIME PURCHASE) • Real radio messages with their surviving keys, from a 1930 training message to May 1945 • Encrypt and decrypt every message • A message sheet in period style to view and share • Dedicated demos for Enigma D, K, G, M3, M4 and T Buy once, no subscription. Profiles, all seven machines and the Enigma I demo stay free. CHECKED AND SOURCED Every simulated machine is tested against surviving radio messages. The app's source list shows where numbers, dates and pictures come from: Crypto Museum, Wikipedia, Frode Weierud, the German Army and Navy key procedures and the Deutsches Museum. NO ADS, NO TRACKING Works offline, only the purchase needs a connection. No account, no data collected. OUR STANCE The Enigma was a tool of war and of the Nazi state. The app shows the technology and its history. It glorifies none of it.

Verdict

The call

The clearest difference is in-app purchases: Enigma Cipher The Unbreakable at none against Enigma's 1. Enigma's advantage is iOS requirement (18.0 vs 26.2). On price, ads and device support there is nothing between them.
