Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureHelp shoppers pick their size before they buy. Start from a ready-made chart for tops, bottoms, kids or shoes, adjust the numbers and choose which products show it: by product, collection, type, tag or vendor. Shoppers open the chart next to the size picker, switch between centimeters and inches, and follow a measuring guide. On phones it opens as a bottom sheet.
Create size charts and display them on relevant product pages. Build tables with a spreadsheet-style editor, match charts to products using vendor and tag conditions, and customize the popup to fit your store. Customers can view measurements on desktop and mobile and switch between centimetres and inches. Track chart impressions and opens, and review suggested matches and conflicting rules.
