Free web tools by RandALL
Random tools that play fair
Spin a wheel, flip a coin, roll dice, pick names or split a group into teams, free in your browser and with no sign-up. Every result comes from your device’s secure random number generator and is decided before the animation starts, so how you tap can’t change it. A list you type once works in every list tool.

RandALL for iPhone
Only in the app
RandALL for iPhone has 25 tools. These ones are only in the app.
Random alarms
Alarms that ring at random times inside the hours you choose. Good for a stretch break, a water reminder or a practice drill.
This or That
Snap two photos and let RandALL pick. Each subject is cut out into a clean sticker, and you can save packs to use again.
Finger Picker
Everyone puts a finger on the screen and one gets chosen, with haptics and sound.
Spin the Bottle
Lay the phone on the table, give it a spin and let it point.
Globe
Spin to land on a random country and see its capital, or swipe the globe and tap to explore.
Real 3D dice and coin
Throw real 3D dice, up to 8 at once, and watch them bounce and land. The coin is a real 3D coin, flipped by the same physics.
How it picks
The same way the app does. Fair is something you can check, so here is the whole recipe.
- The answer is drawn first. Before anything moves, your browser’s
crypto.getRandomValuespicks the result. Rejection sampling throws away the few raw numbers that would give one outcome a rounding edge. - Weights are tickets. An item with weight 3 gets three tickets out of the total, and its wedge gets the same share of the wheel. Nothing else changes the odds.
- The animation only shows it. A wheel that stopped wherever your flick sent it could be aimed. Here the spin is worked out backwards from the answer, so a hard flick and a soft tap are equally fair.

Questions
Are these tools really random?
Yes. Every result comes from crypto.getRandomValues, the random source browsers use for security, with rejection sampling so no outcome gets a rounding edge. The result is picked first and the animation only shows it.
Do I have to pay or sign up?
No. The web tools are free, with no account and no limit on spins, flips, rolls or picks. The one limit is saved lists: the web keeps 3. RandALL on iPhone keeps as many as you like.
Where are my lists stored?
Only in your browser. Saved lists stay in this browser’s storage and are never sent anywhere. A shared link carries the list after the # in the address, a part browsers don’t send to the server.
Is there an Android app?
No. RandALL is iPhone only for now. These web tools are yours to keep using, on any phone or computer.
