Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureMeasura adds a width × height price calculator to your product page. Shoppers type their size in cm, m, inches or feet and see the price before adding to cart — no quote emails. Price by area (per m² or ft²) or by perimeter, set size limits and a minimum price, and add paid extras such as lining or fitting as fixed or percentage add-ons. The size is saved on the order line so production knows what to cut.
This app allows you to generate pricing on the fly! Create unlimited variants (avoid Shopify's variant limit), unlimited options, custom pricing calculations, quotes, bundles, subscriptions, selling plans, and more without having to create a custom app! It is designed to be developer friendly with no rigid templates. Use your own HTML, CSS, and JavaScript formula. Customize it however you wish!

How Shoplist compares apps
Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 14, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
