Spillproof is a field-ready grocery command center for shoppers who want a cleaner list, faster store flow, smarter price decisions, and fewer surprises at checkout.
Build a grocery list with categories, notes, quantity estimates, and prices. Spillproof sorts the list in store-friendly order, keeps checked rows out of the way, and lets you filter by aisle section while shopping.
The Budget tab turns the list into an estimated cart total with category spend, missing-price callouts, and a shareable checkout brief. Checkout Guard adds a readiness score that highlights budget risk, unpriced rows, heavy-spend categories, and price-book signals from your own saved price history.
Use the Price Book to record what common items usually cost, then compare a current price against your history. Use the Compare tab to find the best package by ounce, gram, fluid ounce, liter, or count. Use Cart Split when a household or group trip needs clean per-person totals.
Spillproof also includes a Staples Library for recurring items, a Trip History log for past shopping runs, custom store layouts, CSV export, and a local-first design that keeps shopping data on your device.
