What merchants think

Feedback submitted

Merchants say this app helps customers pick the right size and shop confidently with clear charts, a size recommender, and size insights. They report fewer sizing questions and abandoned carts, and value its flexible, professional templates that match store branding. Many find it easy to set up, stable over years, and suitable for both simple guides and advanced tech-pack use. Support is often described as fast, responsive, and proactive.

The training materials for implementation could be better, but the staff went above and beyond to help me custom code a solution for my product. They also provided invaluable expertise in ensuring my calculations from tech pack size chart to recommendations were accurate.

It’s wonderful to hear our team could go above and beyond with the custom coding and help make sure your tech pack size chart calculations translated accurately into recommendations! Thanks a lot for the 5-star review!

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 size chart and recommender did not appear on the quick add slide draw. Sharky and the Kiwi size developers did an absolutely incredible job of solving the issue. Appreciate the time and effort team!
