Scalechart has been a fantastic addition to our Shopify store. The app works smoothly, is easy to set up, and saves us a lot of time. What really stands out is their customer support. Rabia helped us quickly solve a custom issue on our store and stayed in touch until everything was working perfectly. Fast, friendly, and professional support. Highly recommended for any Shopify merchant!

Honestly, this is the best app out there! I originally downloaded it just for the automatic AI translation feature. Since then, they've released major updates that have turned it into the perfect all-in-one app. The customer service is also outstanding, they even created a custom section I needed for my store. My advice: check it out for yourself!

This app is amazing, the price / quality ratio is out of this world. And the way it works is unbelievable, so easy to use. It has been an absolute gamechanger for me, it saves me a lot of time and money.

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.

There are a lot of apps in the shopify store, a lot of them i really like, but its crazy how one app can do every single work for you without getting more expensive. the value this app offers is immense. i really recommend this app to everyone who wants to reach the next level in his or her business.

Very easy to use and the customer service is amazing. They respond quickly and help immediately with any issue. Definitely recommended!

I have used the app for a few weeks now, and must admit that it is perfect to have for my brand. The owner of the app Gudmand is a legend as well, helps you whenever you need him in his discord app created for the app and is a good guy. With just a few clicks, you have your size chart ready in a professional setting. Keep wasting hours with other size chart apps, this one will change your life.
— AVELYN LONDON
I’m honestly blown away by the support team behind this app. I reached out to ask if they could potentially add a specific language that I needed, and I was shocked when they actually did it! It’s not every day you see developers literally implementing a whole new language just because a user asked for it. The app itself works flawlessly, but this level of dedication to their community is what tr...

This app is amazing. Saved lots of my time. Also Automatic Translation to match your store language is cherry on top
— La Scintilla Firenze
I've wasted more time than I'd like to admit setting up size charts with other apps — this one actually just works. Genuinely the quickest I've gotten a new product collection sorted - very easy to use aswell.
— Monroe & Hayes
Best (fastest) app in the game and they are MUCH cheaper with pricing compared to competitors like Kiwi size chart & BF size chart. RECOMMENDED!
— Sofía Valera
Game changer. Customers actually know their size before buying, so returns dropped and sales went up. Took 5 minutes to set up. Wish I'd found this sooner.
