ShelfPenny: Grocery Price Book

About

ShelfPenny is a personal grocery price book for the prices you observe while shopping. Enter the pack size and price, compare like-for-like unit costs, and keep a practical history for future trips. COMPARE PACKS FAIRLY Compare two to six products across grams, kilograms, millilitres, litres, ounces, pounds or item counts. ShelfPenny normalises each option to a common unit so the result is easy to understand. BUILD YOUR OWN PRICE BOOK Save the store, product, pack size, price, date and an optional note. Over time, your entries create a personal reference based on what you actually saw—not a promise of live retailer pricing. PLAN THE NEXT SHOP Keep favourite items close at hand, then review past observations before choosing a pack. YOUR DATA, PORTABLE Core logging and comparison are designed to work offline. Export or restore your records in portable formats when you want a backup. FREE CORE FEATURES ShelfPenny is free and supported by advertising, with no purchases or subscriptions. Core comparison, history, export, restore and reminder features are never gated by an ad. Prices and availability can change. ShelfPenny performs calculations from information you enter and does not verify retailer prices or guarantee savings.
