Most customers do not know their ring size, so they guess, and a guess often becomes a return. Ringmatch lets them measure instead. They hold any bank card against the screen to set the scale, then match a circle to a ring they own. The answer is checked against the sizes you actually sell, so a customer learns which of your sizes fits and whether it is in stock, then goes straight to it. Nothing is stored or sent anywhere, and the app never reads your products, customers or orders.

• Customers measure their ring size on your product page, nothing to print
• Tells each customer which of your sizes matches, and whether it is in stock
• Selects the measured size in your product's size picker, ready to add to cart
• US, UK, EU and Italian sizes, matched to however you write your own
• Never reads your products, customers or orders, and stores no shopper data
