Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureYou can't fix what you can't measure. Most fashion stores know their return rate, but almost none know what's actually causing it, which products, which sizes, and what it's costing them. That's the part SizeMe shows you. Returns are one of the biggest hidden costs in online fashion, and most of them come down to fit: shoppers order the wrong size, or order two sizes and send one back.
