## What is Mininigma?

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!!

### 4/5 — Toujours pas de son

*2026-09-02*

Depuis la mise à jour de juin et cette dernière mise à jour de septembre, il n’y a toujours pas de son des frappes au clavier

### 3/5 — Latest update

*2026-06-25*

After the latest update the audio is not working. Turning it on/off off/on doesn’t fix it.

### 5/5 — Excellent Enigma emulator

*2026-06-24*

This is a very polished app with great attention paid to fidelity and authenticity. I like that various versions of the Enigma machines are simulated and explained.

### 4/5 — Problème de son

*2026-06-24*

Bonjour, depuis la dernière mise à jour, plus de son des frappes au clavier.

### 5/5 — Fast fix!

*2025-12-17*

Wurde superschnell behoben! Wieder Top!

alter Text:
Schade, fand ich mal super. Aber nun kann man die unteren, mittleren Tasten nicht mehr erreichen, weil der Bereich von der Homegeste beansprucht wird. Und oben verschwindet einiges hinter der Dynamic-Island.

**Developer response:** Könntest du es noch einmal mit dem neuesten Update (4.5.1) versuchen? Ich hoffe, es löst das Problem. Danke! (online übersetzt :)

### 4/5 — Cool, one major flaw

*2025-07-02, version 4.4.8*

The app works really well. I’ve read about the Enigma machine for many years and have become quite familiar with it including how it works. It looks great, too. A great emulator.

Now for the bad part. All the help and tutorials are written in some bogus font that looks like a severely distressed typewriter.  My tired old eyes struggle to read them. If the developers are reading this, please stick to a font that’s readily readable. If it wasn’t for this issue, this would be a five star review.

### 5/5 — Just brilliant!!

*2023-11-20*

This Mininigma App couldn't be more like the real thing. The changeability of the rotors as for u-boats. Luftwaffe, army etc., or just swapping them around is just great, the plugboard is amazing too. The whole enigma simulator App is just brilliant. I have a pile of downloaded copies of WWII German coded messages and the Mininigma decodes them as the real Enigma machine would've done all those years ago. I actually use it to create my most important online passwords, I couldn't be more happier thank you guys, you've done a great job.... PS. Please, please keep it updated.

### 5/5 — Genius App!!

*2021-10-19*

Thanks for doing this! This is an absolutely spectacular app for enigma enthusiasts. It’s the most realistic simulation I’ve ever seen.

### 3/5 — Looks great… but…

*2021-05-06*

This app looks absolutely wonderful… And from my testing, the app performs as advertised. My only real concerns are as follows: 1) The UI does not account for newer devices such as iPhone X as some of the elements are cut off towards the top due to how the screen and Face ID camera are set up. And also 2) The app is not compatible with the voiceover screen reader built-in to iOS. What does those two minor little grapes, great app. The developer should consider making appropriate changes to meet the needs of modern devices as well as make their app slightly more accessible to more users by allowing access via the voiceover screen reader

### 5/5 — Puts a piece of history in your hands

*2020-08-26*

An Enigma wrapped in an app inside an iPhone. 
Outstanding use of the iPhone's technology to explain this technology from World War II. The artwork, use of sound  and animation are excellent. The Bézier curves of the plug cords are an elegant touch. I was particularly happy to see the infamous 4-rotor variant of the machine. I searched the App Store for an Enigma simulator and this does not disappoint. Excellent workmanship. ★★★★★
