Can you solve a problem worth $1,000,000? The Clay Mathematics Institute has offered a million-dollar prize for each of seven unsolved mathematical problems — and nobody has claimed them yet. Millennium Problems brings these mysteries to life for everyone, from curious 11-year-olds to doctoral researchers. SEVEN LEGENDARY PROBLEMS • P vs NP — Is finding as hard as checking? • Riemann Hypothesis — Where do prime numbers hide? • Yang-Mills & Mass Gap — Why do particles have mass? • Navier-Stokes — Can we predict turbulent fluids? • Hodge Conjecture — What shapes are built from algebra? • Birch & Swinnerton-Dyer — How many solutions does an equation have? • Poincaré Conjecture — The shape of the universe (SOLVED!) EVERY SKILL LEVEL Choose your grade — from Grade 6 to Graduate — and the content adapts instantly. The same problem is explained with simple analogies for a middle schooler and rigorous proofs for a PhD student. INTERACTIVE 3D VISUALISATIONS Every problem comes with a real-time Three.js visualisation. Watch elliptic curves rotate, Riemann zeros appear on the critical line, and fluid particle fields swirl — all rendered natively on your device. BUILT-IN QUIZZES Test your understanding with 5 questions per problem per grade level. Earn XP, track your streak, and collect badges as you explore. WORKS OFFLINE No account. No subscription. No ads. Everything runs locally on your device. OPTIONAL BIOMETRIC LOCK Protect your progress with Face ID, Touch ID, or fingerprint — entirely optional. Whether you're a student looking for a challenge, a teacher seeking engaging material, or a mathematician revisiting the classics, Millennium Problems meets you where you are.

About

Quantum Route Finder

Features
Read full description

Quantum Route Finder lets you run real quantum circuits on IBM's quantum computers directly from your iPhone — no simulator, no shortcuts. Your device builds the circuit, submits it to a 156-qubit IBM Quantum processor (Heron r2 generation), and visualizes the measurement results in real time. How it works The app uses a hybrid architecture: your iPhone acts as the controller, constructing OpenQASM circuits and sending them to IBM Quantum Cloud via the REST API. Quantum computation happens on the actual QPU hardware at IBM Research facilities. Everything else — UI, circuit building, result visualization — runs entirely on your device. IBM Quantum account required This app requires a free IBM Quantum account at quantum.cloud.ibm.com. The free Open Plan includes 10 minutes of QPU time per month. This limit is enforced by IBM, not this app. Once your monthly quota is used, jobs will be queued or rejected until the next month. No IBM affiliation — you must create and manage your own account. What you need IBM Cloud API key (free, from quantum.cloud.ibm.com) Instance CRN (from your IBM Quantum dashboard) Available backends ibm_kingston, ibm_fez, ibm_marrakesh (156-qubit Heron r2 processor
