KŌINI Dice is a beautifully simple, provably fair dice roller. Press once and it generates 99 individual six-sided dice rolls — instantly, right on your device. Every roll is created the moment you press the button, using your iPhone's built-in cryptographic random number generator. Nothing is pre-computed, nothing is stored, and there is no pool of numbers to pick from. Each of the 99 results is generated from scratch, in real time. TRUE ENTROPY The randomness comes straight from your device's operating-system cryptographic core (SecRandomCopyBytes). It is never seeded, cached, or reused between presses. EXACTLY FAIR Each die face lands with a probability of exactly 1 in 6. KŌINI Dice uses precise byte-level sampling so no face is ever favored — fairness by construction, not by approximation. COMPLETELY OFFLINE The app never touches the network. It has no ads, no accounts, no analytics, and no tracking of any kind. It collects no data whatsoever. WHAT YOU SEE - One button: Roll 99 - All 99 results, shown roll by roll - Per-face counts and the running total - A clear breakdown of how the entropy engine works Whether you are gaming, teaching probability, settling a decision, or you simply love genuinely fair randomness, KŌINI Dice gives you 99 honest rolls every time — with 6^99 possible outcomes for a single press. No sign-up. No ads. No data. Just fair dice.
