Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureWhen customers pick the wrong size, you lose sales and face costly returns. ScaleChart is a size chart builder that creates custom AI charts and fit advice to reduce returns. Auto-generate a chart from a photo or text, then auto-assign or bulk-apply it across products. Show it in a mobile-friendly popup, tabs, or theme-native dropdown.
Online shoppers can't try items on, so they guess their size — and wrong guesses become returns. SizeGuide adds a "Find my size" button to your product pages. Shoppers answer a few questions and get a clear size recommendation from your own measurement charts, or an AI mode that adapts to fit preferences. Create unlimited charts, assign them by tag, collection, or product, and import sizes from CSV.
- Transform supplier images into professional, interactive size charts instantly.
- Automatically transforms units and languages to match your local market needs.
- Sticky Add to cart included
- Instant size recommendations via a "Find my size" button on product pages
- Smart size grids assigned automatically by product tag or collection
- AI mode powered by Claude for fit-aware, personalized recommendations
- Analytics dashboard to track top sizes and flag return-prone products
