Spillproof: Grocery List and Bill Split

Unit Price Comparator

The Compare tab takes the price and size of two to four packages and instantly shows which is cheapest per ounce, gram, fluid ounce, liter, or count. Supports mass, volume, and count units across any mix of brands or sizes. Highlights the winner and shows how much more the others cost.

Trip History

Every time you clear your checked items, Spillproof silently logs the trip — date, item count, and estimated spend. The Budget tab shows a 30-day rolling total and lifetime average. Tap any trip to label the store. No receipt scanning required.
