Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureGuarantee an ideal fit with our pre-designed measurement blocks, created specifically for stores that sell press-on nails. Seamlessly integrate these blocks into your Thank You and Order Status pages to collect nail size details after purchase. Each block includes a QR code that guides customers through the sizing process, making it quick and easy to provide accurate measurements.
Fit uncertainty is why shoppers do not purchase, and fit issues are why they do not return to your store. RealSize replaces your static size chart with a personalized size recommendation, generated from a quick scan with your shopper's mobile phone, and shown right on the product page. Merchants use RealSize to cut fit-related returns, lift add-to-carts, and stop losing shoppers due to fit uncertainty.
