Free utility tools
Small, fast helpers for everyday tasks: make a QR code, let a wheel pick a name, split a class into teams, flip a coin, roll dice or draw random numbers. No accounts and nothing to install.
Every tool in this category is free, needs no account and runs on your device. New tools are added as people ask for them; suggest one.
About the utility tools
The utility tools are the small helpers people reach for once a week: a QR code for a link, a Wi-Fi password or a contact card; a wheel that picks a name or settles a yes-or-no question; a team generator that deals a class into fair groups; a random number, a coin and dice. They are built to be fair and to be honest about it: every random result comes from the browser’s cryptographic random generator, with no bias towards any slice, number or side, and the wheel chooses the winner before it starts turning rather than stopping wherever it lands.
The QR code generator makes a code that holds the content itself, so it never expires and nothing about it is tracked. It supports dot and corner styles, colours, a logo, a frame with a caption, and reads every design back with a scanner before it says the code will scan. Arabic, Urdu and emoji encode correctly, which many generators get wrong.
Frequently asked questions
Does the QR code stop working after some time?
No. The code holds the text itself, not a link to this site, so it works for as long as the address or the Wi-Fi network it points to exists. There is no account and no expiry.
Is the wheel really random?
Yes. The winner is drawn with the browser’s cryptographic random numbers, with each name equally likely whatever the size of its slice, and only then does the wheel turn to it. The names you enter are kept on your device so they are there next time.
How does the team generator keep teams fair?
It shuffles the names and deals them like cards, so team sizes differ by at most one and no name is more likely to land in any team.
Can I save or share a wheel?
Yes. The names are kept in your browser, and the share link carries them in the address after the # sign, so nothing is stored on a server.
