Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSizing uncertainty is a top cause of returns and abandoned carts. FitGenius adds a size recommendation widget to product pages: shoppers answer 3 quick questions on height, build, and fit preference, and get a recommendation with a confidence score and reasoning. Unlike static size charts, recommendations are specific to each product. Build size charts from templates, CSV, or manual entry.
Shoppers can't try clothes on through a screen, so they guess, order two sizes, and send one back. Robosize fixes both halves of that. Virtual try-on lets them see your garment on their own body. AI size recommendation tells them which size to pick, using height, weight and age. No tape measure. Set up one product and every other item in your store maps automatically. Works on any apparel store.

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 13, 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.
