Many Worlds generates quantum random numbers using your iPhone camera. Your camera sensor is a grid of millions of tiny light detectors. At quantum scales, light shows up as individual photons, and there's no way to predict exactly how many will hit a given pixel during an exposure. Many Worlds takes a single dark frame at minimum exposure and uses the quantum random result to get a stream of over 200,000 clean quantum-random bits. FEATURES Coin Flip: Flip a quantum coin. The outcome comes from actual photon arrivals at the sensor, not from a pseudorandom algorithm. Your recent flips are tracked in a history view. Lottery Numbers: Generate Powerball tickets using the combinatorial number system, seeded by quantum random values. Each ticket maps to one of 292 million possible combinations with uniform probability. Random Digit Table: A 20x20 grid of quantum random digits, styled after the RAND Corporation's famous 1955 reference book. Digits are grouped in blocks of five for readability. Dice: Roll a D6 or D20. Rejection sampling makes sure every face is equally likely, with no modulo bias. Quantum Alarm: Set a time range and let the universe pick when your alarm goes off within that window. Works with both absolute time ranges and relative durations. You can snooze and dismiss from the lock screen. THE PHYSICS Under the Many Worlds interpretation of quantum mechanics, every quantum event causes the universe to branch. All outcomes actually happen, each in its own branch. So when you flip a coin in this app, both Heads and Tails really do occur. You're just finding out which branch you are in. The quantum events that produce the randomness have already occurred by the time the sensor is read out. The branching happened at each photodiode. So the result you see isn't causing a split. It's telling you which branch you're on. When you act on the result, what was a quantum-scale difference becomes a macroscopic one. This app doesn't create the branching. It takes a branch that already exists and gives it a role in your life. PRIVACY No data collection. No analytics. No network requests. No accounts. Everything happens on your device. The camera is only used for quantum noise extraction. No images are stored or transmitted.
