This app has been such an important addition to our store. The size charts are professional, and the recommender gives our customers the confidence they need when placing their orders. It has also helped minimize sizing questions and reduce abandoned carts by providing shoppers with the information they need to order with confidence. I've had a few questions along the way, and their customer service has always been responsive and helpful!

It’s great to hear Kiwi’s size charts and recommender are giving shoppers more confidence while reducing sizing questions and abandoned carts. We appreciate Kiwi being an important part of your store over the past eight months!

Overall a great app with very helpful support.
Some things to mention -
1. the settings could be more user friendly with more design options that does not require use of CSS.
2. Most importantly - the localization options are limited. If you are running a store with a less known language, you might have some trouble localizing. That being said, hopefully more default languages (or an option to set up a custom language) will be added soon.

Otherwise, it is great!

The base app is decent, but false advertising will lead you to buying the upsell.

The translate feature clearly says "Translate your size charts and recommenders". However when you buy it and hit translate, it only translates the buttons and header.
- Content inside the size guide is not translated
- Shopify's native "Translate & Adapt" can't touch it
- Support told me you can't create per-locale Size guides, so there's no workaround

Their recommendation was to use another $40/mo translation app.

Thank you for laying this out so clearly. We’re sorry the translation feature did not meet what you expected, especially around size guide content and per-locale guides.

Our management team has followed up with you directly to review the situation, clarify the current limitations, and see how we can make this right. We’re also using your feedback to improve how Kiwi explains translation support so merchants have a clearer picture before upgrading.

Incredible app and customer service. Been using a Kiwi size calculator for my size guide page and my customers have told me how wonderful it is. I needed to restyle the colors of the app with new branding and was having difficulty. Markson went above and beyond to help me correct the issues I was having. Can't say enough good things, will continue to use this app for my clothing business.

Markson will be happy to know his help with the new branding colors made a difference, and we’re excited to keep supporting your clothing business.

I’ve been using KIWI for a full four years, but please take note: they refuse to export the data you’ve created on their platform. This clearly appears to violate principles around data portability under privacy policies or terms of service. If you don’t want to end up like me—unable to export your data after years of use—please choose carefully.

Four years of work is a serious investment, so we understand why this feels so frustrating. Not having a straightforward export option isn’t ideal, and we hear your concern around data portability.

We have reached out to you through your support ticket to explain the current situation. While a full export feature isn’t available yet, we are working on extracting the core data from your charts so you don’t lose what you’ve built. It may not come in a perfectly portable format, but the focus is on making sure your work remains accessible.

We’re continuing to coordinate this internally and will follow up with a clear update and timeline. Your feedback here is important, and it’s helping push improvements in this area.

Great app, even better support!

We ran into a tricky technical issue with the size chart rendering on our theme, and Reg worked on it for weeks until it was properly fixed.
Never rushed, always responsive, and delivered a clean solution.

That kind of dedication is rare. Five stars well earned!

Thanks a lot!

That sounds like a frustrating issue to deal with, so it’s great to hear Reg stuck with it and got everything working smoothly in the end. We really appreciate you calling out the time and care he put in, especially with something as tricky as theme compatibility.

Thanks for trusting Kiwi and for the kind words!

Kiwi size chart is a very powerful app that we have been using for some time now. The app gives the ability to add sizing details into a clear, responsive table as well as give the customer an option to display in different units such as CM & Inches, which is a huge feature. Their customer service is great as well. We recently had a conflict arise with a new Shopify theme, and the Kiwi team worked with us extensively to create a solution for us.

Hearing that Kiwi has been part of your setup for a while really means a lot. It’s great to know the size chart tables and unit switcher between cm and inches are making things clearer for your customers.

We also appreciate you sharing that experience with the Shopify theme conflict. Those situations can be tricky, so it’s good to hear our team was able to work through it with you and land on a solution together.

Thanks for sticking with us and for taking the time to share this 🙏

Sharky is very helpful. Please provide more training for Markson, as he needs improvement as a customer service agent.

Do NOT use this app! Support is very bad, and if you are doing bigger sales, they will charge way too much. This is a very basic app that can quickly cost you hundreds a month. (without you knowing about it) Stay away!!!!
