Spin Cycle: every washer and dryer in your hall, live In a student hall, 300 people share 8 machines. You walk down three floors to find them all busy, and when one frees up, the last person's wet load is on the floor. Spin Cycle puts every machine online. Twist the dial on any free one and it's yours. When it's done you get a text, and a free dryer is held for you for 10 minutes. Leave it too long and the next resident can move it to the shelf by the door, and you're told where it went. If every machine is busy, join the queue and the next free one is held for you. Two fault reports take a machine off the booking sheet and open a facilities ticket. At 07:00 on a rainy day, residents are told to book a dryer early. Every Monday, facilities get last week's loads and downtime. Try it with no login: open the link, twist the dial, then press Demo → +1 hour and watch the house rules run. The rules really run; the clock and the texts are simulated, and nothing is sent. The rules that the whole hall shares run on Base44's database. Two residents reporting a machine take it off the booking sheet for everyone, and when anyone finds a match for your lost sock, you get a text. Designed and built with Claude Code, and published on Base44 with the Base44 CLI. https://spincycle.base44.app · Walkthrough video attached
