Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureHelp shoppers find the right size & fit in under 15 seconds. Fit Quiz gives personalized clothing & footwear recommendations at the SKU-level using real fit data. It covers size, fit, width, and length for each product. Shoppers do not enter weight, height, age, body measurements, or body scans. It supports unisex sizing and 20 languages. Customize the design to match your brand.
Size guides show specs. TrueFit shows reality. When production arrives, measure each garment and clasify it — runs large, true to size, or runs small. A dynamic widget on your product page shows shoppers exactly how it fits, with model measurements, your recommendation, and a style tip like "prefer a relaxed fit?
