The short answer
Head to head
Standard

Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureExpress wallets — Shop Pay, PayPal, Apple Pay, Google Pay — skip your address form, so orders arrive with a street but no house number, or no postal code at all, and the delivery fails. A missing house number only produces a warning at checkout, which the buyer can ignore. This app turns it into a block: checkout cannot be completed until the address is fixed, wallets included.
