Pick a random item from a list with a spinning wheel animation. Type one item per line, click "Spin", and the wheel rotates to a random winner. Common uses: classroom random-call, YouTube / Instagram giveaway winners, restaurant choice, team picking, decision-making.
Lists stay in your browser — they are not sent to a server. The wheel uses a physics-based spin (fast start, slow stop) for a satisfying result.

When to Use a Decision Maker, and When You Should Trust Yourself
A decision maker is a tiebreaker, not a replacement for judgment. Here is when it actually helps (analysis-paralysis on equal options, breaking a long deadlock, choosing between two equivalent things), and when it makes things worse (when one option is clearly better, when you have not done the analysis, when the decision matters and you need to own it).
