AI size charts and a fit recommender reduce returns. Cart & post-purchase upsells raise order value.

When 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. Add image and color swatches, a sticky add-to-cart bar, cart upsells, and one-click post-purchase offers. Replaces 5-6 apps with unit conversion and translations.

I've tried a lot of Shopify apps, but ScaleCart is easily the best one I've used. The size charts, cart customization, sticky cart, and post-purchase upsells are all top-tier.

Instead of needing multiple apps, ScaleCart does everything in one place. Honestly, I wouldn't recommend any other cart app over it.
