Porch Light

How much Halloween candy do you actually need? Set your porch-light hours and a guess at the crowd, and Porch Light models the trick-or-treat rush in 5-minute steps, drains the bowl over the evening, tells you when you'd run out, and turns it into a shopping list.

๐ŸŽƒ Halloween

A planning toy, not a census: the rush is a bell curve around your peak time, scaled by your own estimate (last year's count is the best guess) and a weather factor. Prices are examples. Edit them to match your store. Nothing leaves your browser.

Your porch

No idea? Quiet street 30โ€“80 ยท typical suburb 80โ€“200 ยท destination block 300+.
