DigiDecoder vs Enigma

DigiDecoder is a universal ham radio digital modes decoder and encoder. Use the built-in microphone or connect an audio cable directly for better input quality. One app for all the signals! The correct digital mode is automatically recognized and decoded in real time with an animated waterfall display. Quickly encode and send beautiful SSTV images, plus CW, FT8, and Packet messages. Bluetooth and network TNCs for Packet are supported as well. Try DigiDecoder free for 7 days. After the trial, continue with an affordable monthly subscription, or unlock lifetime access with a one-time purchase (a few months' worth). Nothing is charged during the trial and you can cancel anytime.

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.
