Zizr — Sizing, no measuring

Zizr is a Shopify App designed to provide precision sizing recommendations for clothing and shoes without the need for body measurements. It offers individual, SKU-level size suggestions on product pages, adapts across brands and categories, and updates based on purchase and fit feedback. Returning customers receive personalized suggestions, while new shoppers can input their current size and fit preference to receive recommendations. The app syncs the product catalogue automatically during setup for up-to-date information.
