Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSize Buddy adds a Find my size button to your product pages. Shoppers answer a few quick questions, like height and weight or bust and hips, and get a size from your own size chart, with a clear explanation of how it fits. Start from a template for tops, bottoms, dresses, bikini tops or one pieces, adjust each size with sliders, and test any shopper before you save.
Size Guide Studio helps clothing, footwear, and accessory stores reduce sizing-related returns. Its built-in size recommender suggests the right size for each shopper — from body measurements, or from height, weight and fit preference. Build size charts by hand or extract them automatically from product descriptions, and bulk-build guides across your whole catalog in one click.
