ShelfPenny: Grocery Price Book

Turn your own shelf-price observations into a practical grocery price book.

ShelfPenny helps you record product, store, price, pack size and timestamp, then compare two to six compatible items on a per-kilogram, per-litre or per-item basis.

COMPARE CONSISTENTLY
• Record the price and pack quantity you see
• Compare compatible weight, volume or count units
• Keep product and store details together
• Use your saved observations when planning your next shop

KEEP A PERSONAL PRICE BOOK
• Save favourites for quick reference
• Search and filter your observation history
• Export a CSV
• Create or restore a JSON backup
• Schedule an optional local weekly reminder

LOCAL AND ACCOUNT-FREE
No account or cloud sync is required. Your grocery records stay on your device unless you explicitly export them through a destination you choose. The advertising SDK processes its own data as described in the privacy policy.

EVERY FEATURE IS FREE
No paid download, purchases, subscriptions, trials or paywalls. Advertising supports the app, with consent requested where required. Optional rewarded ads change only a cosmetic card theme and never unlock a core feature.

Prices are personal observations, not live retailer data. Always verify the current shelf label, package quantity and checkout price. ShelfPenny is not affiliated with supermarkets and does not guarantee savings.
