Sortis
Every draw leaves proof.
I built Sortis as a random picker you can actually verify: wheel, dice, coin, teams, raffle, running order, and numbers, all in one app. Every draw publishes a hash before it happens and reveals its seed after, so anyone can reproduce the exact result instead of just trusting it. It's free to use, with no accounts, no ads, and no subscription, just an optional one-time tip if you want to support it.
Features
What you can do with Sortis.
Seven ways to decide
Wheel, dice, coin, teams, raffle, running order, and numbers all live in one app, so you don't need seven different tools for group decisions.
Every draw leaves proof
Sortis publishes a hash before the draw and reveals the seed after, so anyone can reproduce the exact result and confirm nothing was changed after the fact.
Save your lists, reuse them
Type a class roster, a team, or a raffle list once, save it as a pool, and pull it into any draw mode later without retyping a single name.
Free, private, no subscription
Every feature works fully offline with no account and no ads. Support is entirely optional: a one-time tip if you want to say thanks, never a recurring charge.
