BrainHack vs QuantumPass
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
BrainHack
This app serves as an interpreter for the esoteric B*******k programming language. It allows users to execute B*******k code, which is known for its extreme minimalism and is designed for programmer challenge and amusement rather than practical use.
- B*******k programming language interpreter
- Execute esoteric code
- Minimalist programming language support
- ASCII character output
- Byte input and manipulation

BrainHack is an interpreter app for B*******k. The B*******k programming language is an esoteric programming language noted for its extreme minimalism. It is a Turing tarpit, designed to challenge and amuse programmers, and was not made to be suitable for practical use. It was created in 1993 by Urban Muller. Commands: > increment the data pointer (to point to the next cell to the right). < decrement the data pointer (to point to the next cell to the left). + increment (increase by one) the byte at the data pointer. - decrement (decrease by one) the byte at the data pointer. . output a character, the ASCII value of which being the byte at the data pointer. , accept one byte of input, storing its value in the byte at the data pointer. [ if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command. ] if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.

QuantumPass brings two worlds together: a password and key generator, and a small lab to discover quantum randomness. GENERATE • Passwords from 8 to 64 characters: lowercase, uppercase, digits, symbols, ambiguous-character exclusion, forbidden characters and required characters. The estimated entropy is shown with each result. • Diceware passphrases of 3 to 10 words, in French or English depending on the app language, with the separator of your choice. Strengthen a phrase with randomly drawn capitals, substitutions and suffix. • QRNG: 1 to 100 random bits, in binary, decimal, hexadecimal or Base64. • Blockchain RNG: 128 to 512-bit values in Hex, Base64 or Base58, for your keys and seeds. • All these values come from Apple's cryptographic generator. UNDERSTAND • BB84 demo: follow the key exchange between Alice and Bob, and watch Eve the eavesdropper given away by the error rate. • Qubit Lab: measure a simulated qubit in the Z or X basis and watch the statistics build up. • Bloch sphere: set the θ angle and compare theoretical probabilities with measured frequencies. • Reproducible mode: a seed to replay the same demonstration, in class or in a workshop. • PRNG vs TRNG: two animated panels to see the difference between simulated and hardware randomness. • Built-in tutorial and a 10-question quiz. PRACTICAL • Secure clipboard: whatever you copy stays on the device and is cleared after 60 seconds. • In French and English, on iPhone, iPad and Mac. • Tip Jar: support development right from the app. PRIVACY QuantumPass works offline. All calculations are performed on your device. No account, no ads, no data collected. QuantumPass is an educational tool: its "quantum generator" is a simulation, fed by the system's secure random source.

Verdict
The clearest difference is in-app purchases: BrainHack at none against QuantumPass's 3. BrainHack also leads on update cadence (every 6 weeks vs every 10 months) and iOS requirement (8.0 vs 17.6). On price, ads and device support there is nothing between them.
