Build measurement tables directly from your Shopify admin, with up to 20 columns and 200 size rows in cm or inches. Search products and collections, then assign charts. Add the app block to a compatible Online Store 2.0 product template to show a 'Size guide' modal with unit conversion. Export charts to CSV. No customer or order scopes are requested; app-proxy identifiers are processed transiently for signature verification and are not stored.
