8. App details
Long-form descriptionNorn Fit
Norn reads your size charts and recommends each shopper's size, fewer wrong sizes, and fewer returns. Upload an image or PDF and Norn turns it into a sizing grid you review and publish. Then surface that recommendation anywhere: the product page, a customer account, a returns portal, or your own stack through our REST API. Matching stays server-side, your chart is the single source of truth, and nothing's locked in, your sizing and results are yours to query and export.
ScaleChart
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.
