QuantumBob puts real quantum physics in your hands. Compete against Alice, an AI that uses actual entanglement data from IBM's quantum processor, by guessing measurement outcomes. Can you beat the quantum advantage? PLAY REAL QUANTUM DATA Every round, a real quantum computer has already measured an entangled particle pair. You guess the result — 0 or 1. Alice reads her linked particle and makes the same prediction. The quantum correlations give her an edge that no classical strategy can match. THE QUANTUM ADVANTAGE Without quantum physics, the best any strategy can achieve is 75% accuracy. But Alice's entangled particles push her to about 85%. That 10% gap is physically impossible without quantum mechanics. You'll see it happen in real time as you play. FEATURES - Real quantum measurement data from IBM's Marrakesh quantum processor - Compete against Alice's quantum-powered AI in 10-round ranked games - Challenge friends with local pass-and-play multiplayer - Learn quantum concepts as you play with contextual tips - Track perfect rounds, win average, and Alice's accuracy over time - Explore interactive lessons on entanglement, Bell's theorem, and the Tsirelson bound - Compare real quantum data against classical fakes side by side - Run built-in statistical proof tests that verify the quantum advantage - Game Center leaderboards to compete globally NO PHYSICS DEGREE REQUIRED QuantumBob starts from zero. The interactive tutorial walks you through everything — from "what is 0 and 1?" to "why can't I beat 75%?" to "what makes quantum special?" You'll understand entanglement through playing, not studying. THE SCIENCE BEHIND THE GAME QuantumBob is built on the CHSH Bell experiment, one of the most important experiments in quantum physics. In 2022, the Nobel Prize in Physics was awarded for work proving that quantum entanglement violates Bell inequalities — exactly what you experience every time you play. All quantum data comes from real IBM quantum hardware. No simulations, no random number generators — actual measurements of entangled qubit pairs. Download QuantumBob and discover why quantum physics breaks the rules.

CryptoKit hands you a final hash or ciphertext and hides everything in between. GLASSBOX rebuilds each algorithm by hand so every intermediate value is visible, tappable, and provably correct against Apple's real implementation — then lets an on-device AI try to crack it, winning on the weak and drowning on the strong. Honesty is a hard requirement. No screen ever fakes progress against strong crypto. Where AI or brute force cannot win, the app shows it failing and explains why. The hand-written teaching engine is checked byte-for-byte against Apple's real CryptoKit/Security output — if they ever disagree, a test fails. WHAT YOU CAN DO • Classical ciphers — Caesar, ROT13, Vigenère, XOR — with an on-device AI cracker that breaks them from ciphertext alone using real statistical cryptanalysis. • Modern families rebuilt by hand and verified against the real thing: AES-128, ChaCha20, DES; SHA-256/512, SHA-1, MD5; RSA, ECC, X25519. Scrub AES through its 10 rounds, step RSA one exponent bit at a time, watch SHA-256 churn its state. • The avalanche on camera: flip one input bit and about half the digest flips. • Crack, Tamper, and Breach labs — a dictionary attack cracks weak passwords instantly while a real, device-timed Argon2id shows why strong hashing takes centuries. • Labs of physics and math: a thermodynamic crack lab, a quantum threat layer (Shor/Grover verdicts + post-quantum survivors), an entropy forge that harvests real sensor noise, and Rosetta panels showing the same cipher in Swift, Python, and C++. • The AI, honestly: a hand-written deep net genuinely learns a reduced-round distinguisher — then genuinely fails at full strength, forever. The flat line is the exhibit. • Hermes — a persistent learner whose brain grows across sessions and syncs across your devices via iCloud. PRIVACY All cryptographic computation runs on your device; your inputs never leave it. The only network traffic is optional iCloud sync of the app's own learning data (in your private iCloud database) and anonymous crash/diagnostic reporting. No accounts, no ads, no tracking.

Verdict

The call

Quantum Bob and GlassBox Dev are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
