Is that bigger pack really better value? Compare prices you've recorded, check receipts against saved shelf offers, and shop with more confidence. Stop guessing which groceries are better value. Pennumi helps you compare the prices you record across stores and package sizes, remember what you paid, and check eligible shelf offers against your receipts. Build a private grocery pricebook on your iPhone, so your next shopping decision is based on more than memory. COMPARE VALUE, NOT JUST THE PRICE TAG Is the bigger pack really a better buy? Pennumi compares unit prices across package sizes and stores, helping you see which of your recorded options offers better value. TURN SHELF PHOTOS INTO USEFUL PRICE RECORDS Photograph a product and its shelf label, then review and confirm the price, package size, sale terms, and loyalty requirements Pennumi extracts. Scan product barcodes to keep track of the items you buy. CHECK SHELF PRICES AGAINST YOUR RECEIPT Did you get the sale price you expected? Add a receipt, confirm each product line, and link purchases to matching shelf offers. When the saved offer applies, Pennumi helps you review possible missed sale or loyalty prices, with the original shelf photos and receipt images available to check. PLAN YOUR NEXT SHOP WITH WHAT YOU KNOW Use prices you have personally recorded to plan a one-store shop or compare shopping across several stores. Build your pricebook around the products you buy and the places you shop. KEEP YOUR SHOPPING RECORDS TOGETHER Save multi-page receipts, store details, payment types, and loyalty-point activity in one place. Keep loyalty-card barcodes in protected storage on your iPhone. YOUR PRICEBOOK. YOUR CONTROL. Your pricebook is stored on your iPhone. Export your records or delete all local Pennumi data whenever you choose. Start with the groceries you buy most. Build your pricebook as you shop, and bring a clearer picture of value to your next trip. GOOD TO KNOW Pennumi compares prices you record and confirm; it is not a live retailer price feed. Automated extraction can make mistakes. Review product identity, package sizes, offer terms, and receipt details before relying on a record. Prices and offers can change, and Pennumi does not guarantee current prices, availability, offer eligibility, or the final checkout amount.
