Secure Enclave
Hardware randomness from the dedicated security chip in your iPhone. Works offline, returns instantly, and is the default for every roll.
Now on the App Store
Roll with intent.
Every dice app hides a rand() call. Quantum Dice Roller makes the randomness
a visible choice: pick where your bits come from, and the app shows you exactly what
produced the roll.
Android soon An Android version is in development.
Randomness drawn from the physical world rather than a formula — every roll a genuine collapse of possibility.
Choose your source
Four ways to make a number
Each source is real, and each one is selectable before you roll. The dice maths sits on top of whichever you pick, using rejection sampling so the result stays unbiased.
Physical · optical
Lens QRNG
Photon shot-noise sampled through the camera sensor — genuine physical randomness from light itself. Frames are read for noise and discarded; nothing is saved.
Public · verifiable
NIST Beacon
A signed public randomness pulse from the U.S. National Institute of Standards and Technology. Anyone can independently verify the pulse your roll used.
Coming soon · cloud hardware
IBM Quantum Cloud
The deepest source: send a sampling circuit to a real superconducting quantum processor on IBM Quantum Cloud and roll on what comes back — bits from genuine qubit measurement rather than a simulation of one. Connect your own IBM Quantum credentials, and the roll is tagged with the backend that ran it.
Provenance
Every roll carries a receipt
When the app rolls, it stamps the result with a SHA-256 hash of the exact bytes it consumed, tagged with the source that produced them. Your history shows what actually happened, roll by roll.
That honesty matters most when something goes wrong. If a source is unreachable or its entropy fails a health check, the roll falls back to the Secure Enclave — and says so. A roll that reads "Lens QRNG unavailable — rolled on Secure Enclave" is telling you the truth rather than dressing up a substitute.
Privacy
Nothing to collect
No accounts, no analytics, no ads, no third-party trackers. Your roll history stays on your device. The app has no server of its own.
