Fitto ‑ Size Charts & Guide

Fitto ‑ Size Charts & Guide is designed to help merchants reduce size-related returns by making sizing information easier for shoppers to understand. The app lets merchants create size charts in a simple grid, paste data from spreadsheets, or start from templates, then assign those charts automatically to products, collections, tags, product types, SKUs, or vendors. Shoppers can view the size guide in a pop-up, switch between centimeters and inches, and use it on mobile, which supports a smoother buying experience. Overall, the app appears focused on improving fit confidence and reducing hesitation at checkout, but there are not enough reviews to analyze right now.
