Frequently Asked Questions

Can barcode scanner apps find prices at local stores?

ShopSavvy shows prices at nearby physical stores in addition to online retailers. This is particularly useful for large purchases where local store availability and price matters. Coverage varies by location and which retailers participate.

Do iPhone cameras scan barcodes natively?

Yes. The iPhone camera app automatically detects QR codes and many barcodes — a notification appears with the barcode content or link. For more advanced scanning with price comparison, install ShopSavvy or Amazon Shopping.

How much can I save using price comparison while shopping?

Savings vary significantly by product category. Electronics often have 20-40% price variation between retailers. For commodities like cleaning products and food items, savings are smaller. The biggest savings come from checking Amazon vs. big-box store prices on larger purchases.
