Did you know that you are carrying a 3D magnetometer? That you can use your phone as a pendulum to measure earth's local gravitational acceleration? That you can turn your phone into a sonar? phyphox gives you access to the sensors of your phone either directly or through ready-to-play experiments which analyze your data and let you export raw data along with the results for further analysis. You can even define your own experiments on phyphox.org and share them with colleagues, students and friends. Selected Features: • A selection of pre-defined experiments. Just press play to start. • Export your data to a range of widely used formats • Remote-control your experiment through a web interface from any PC on the same network as your phone. No need to install anything on those PCs - all you need is a modern web browser. • Define your own experiments by selecting sensor inputs, defining analysis steps and creating views as an interface using our web-editor (http://phyphox.org/editor). The analysis consists of just adding two values or using advanced methods like Fourier transforms and crosscorrelation. We offer a whole toolbox of analysis functions. Sensors supported: • Accelerometer • Magnetometer • Gyroscope • Pressure • Microphone • Proximity • GPS • Camera • LiDAR/ToF *some sensors are not present on every phone. Export formats • CSV (Comma separated values) • TSV (Tab-separated values) • Excel (if you need other formats, please let us know) This app has been developed at the 2nd Institute of Physics A at the RWTH Aachen University.
Enigma Simulator
This app simulates the Enigma cipher machine, a historical device used for encryption and decryption. It demonstrates how the machine's rotors, plugboard, and indicator lights work to create complex ciphers, making frequency analysis ineffective.

Enigma密码机 在密码学史中,恩尼格玛密码机(德语:Enigma,又译哑谜机,或“谜”式密码机)是一种用于加密与解密文件的密码机。 确切地说,恩尼格玛是一系列相似的转子机械加解密机器的统称,它包括了许多不同的型号,为密码学对称加密算法的流加密。 键盘一共有26个键,键盘排列和广为使用的计算机键盘基本一样,只不过为了使通讯尽量地短和难以破译,空格、数字和标点符号都被取消,而只有字母键。 键盘上方就是显示器,这可不是意义上的屏幕显示器,只不过是标示了同样字母的26个小灯泡,当键盘上的某个键被按下时, 和这个字母被加密后的密文字母所对应的小灯泡就亮了起来,就是这样一种近乎原始的“显示”。 在显示器的上方是三个直径6厘米的转子,它们的主要部分隐藏在面板下,转子才是“恩尼格玛”密码机最核心关键的部分。 如果转子的作用仅仅是把一个字母换成另一个字母,那就是密码学中所说的“简单替换密码”,这就是“恩尼格玛”难以被破译的关键所在,这不是一种简单替换密码。 同一个字母在明文的不同位置时,可以被不同的字母替换,而密文中不同位置的同一个字母,又可以代表明文中的不同字母,字母频率分析法在这里丝毫无用武之地了。 这种加密方式在密码学上被称为“复式替换密码”。 使用“恩尼格玛”通讯时,发信人首先要调节三个转子的方向(而这个转子的初始方向就是密匙,是收发双方必须预先约定好的), 然后依次键入明文,并把显示器上灯泡闪亮的字母依次记下来,最后把记录下的闪亮字母按照顺序用正常的电报方式发送出去。 收信方收到电文后,只要也使用一台“恩尼格玛”,按照原来的约定,把转子的方向调整到和发信方相同的初始方向上,然后依次键入收到的密文, 显示器上自动闪亮的字母就是明文了。加密和解密的过程完全一样,这就是反射器的作用,同时反射器的一个副作用就是一个字母永远也不会被加密成它自己, 因为反射器中一个字母总是被连接到另一个不同的字母。 而除了转子方向和排列位置,“恩尼格玛”还有一道保障安全的关卡,在键盘和第一个转子之间有块连接板。 通过这块连接板可以用一根连线把某个字母和另一个字母连接起来,这样这个字母的信号在进入转子之前就会转变为另一个字母的信号。 这种连线最多可以有六根(后期的“恩尼格玛”甚至达到十根连线),这样就可以使6对字母的信号两两互换,其他没有插上连线的字母则保持不变。 ——当然连接板上的连线状况也是收发双方预先约定好的。 就这样转子的初始方向、转子之间的相互位置以及连接板的连线状况就组成了“恩尼格玛”三道牢不可破的保密防线, 其中连接板是一个简单替换密码系统,而不停转动的转子,虽然数量不多,但却是点睛之笔,使整个系统变成了复式替换系统。 连接板虽然只是简单替换却能使可能性数目大大增加,在转子的复式作用下进一步加强了保密性。

Verdict
The clearest difference is review sentiment: phyphox at 79% against Enigma Simulator's 0%. phyphox also leads on rating (4.6 vs 4.0) and in-app purchases (none vs 1). On price, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Enigma Simulator sells 1 one-off in-app purchase. phyphox asks for nothing beyond the download.
phyphox holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: phyphox has 276 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 79% of phyphox's written reviews are positive against 0% of Enigma Simulator's.
phyphox ships an update every 3 months, Enigma Simulator every 6 months. The most recent releases landed on October 1, 2026 and September 18, 2026 respectively.
