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. When customers pick the wrong size, you lose sales and face costly returns.

Very good app, support has been amazing!
Wow!! What a perfect app this is. First of all, the support. I have never experienced such good support. Nothing is too much trouble, everything is possible, and they respond super fast. The app has everything you need. From shopping cart to after-sales, it has it all. I highly recommend this Shopify app!
App works really great and very helpful for our e-com store. They also have a very accommodating support team we can ask for help anytime. Thanks, Rabia!
It is a great app. You have it all together, like swatches, bundles, size chart, etc. Service is perfect.
I’m very happy with ScaleChart. The app offers so many useful features and possibilities, and it makes managing things like size charts and other product page features much easier. What really stands out to me is the customer support. Whenever I have a question or run into a problem, they respond incredibly fast. They’re also genuinely friendly and actually take the time to help you properly instead of just giving a standard answer. They even give useful advice on how to improve or set things up better. Overall, a great app with lots of possibilities and even very friendly support. Definitely recommend it!
I really like this app, so many options to customize your store from swatches, size chart, cart, upsell. Highly recommend and their support is amazing as well!
