SPIN is a shareable decision wheel for small group decisions: dinner, games, chores, watch lists, and anything else that gets stuck in chat.
The current version uses a modern two-panel tool layout with the wheel always visible, shareable URLs that preserve the current question and options, local save and restore, quick-start presets, recent pick history, shuffle, fullscreen, and mobile-friendly controls.
Built on Next.js 16 with TypeScript, Tailwind CSS, and immediate SVG wheel rendering with reliable winner selection.
