Ultimate Size Chart

Title: Poor Support & Non-Functional App – Avoid

I installed the Ultimate Size app hoping it would help streamline sizing for our customers. Unfortunately, the app never worked as expected — charts wouldn't load properly, and integration was inconsistent across product pages.

What’s worse is the complete lack of support. I’ve contacted the developers multiple times over the past two months with no reply whatsoever. Not even an acknowledgment. For an app that’s supposed to enhance the customer experience, it has done the exact opposite.

It’s incredibly disappointing to see such poor service, especially for a paid app on the Shopify ecosystem. If you're considering this app, I strongly recommend looking elsewhere — there are better alternatives with actual support and working functionality.

Until the issues are fixed and the team starts responding, this app is a waste of time and money.

Very bad customer support. all of sudden app does not work, no one care to fix it

I wish I could leave a good review because it looks like a nice app but unfortunately after I have installed it a few days ago I am still having an issue on mobile and iPad version... i tried to get in touch with support and as of today I still did not get any answer... now my 3 days trial is over and I guessed I will be charge for an app that simply did not work as expected... waste of money and waste of time...

We have been trying to contact support for over a month. We tried all emails and contact form that we were able to find in their app. No one ever answered. Buyers beware!

Size chart is very glitchy and customer service is horrible. I do not recommend this app to anyone.

Unbelievable customer service. Our store required a unique installation, this was handled with ease and outstanding care. I highly recommend doing business with the Ultimate Size Chart team, you won't be disappointed.

The app is easy to use and it does what it's supposed to. The grouping feature is also very useful, allowing us to select multiple products and group them with the same size guide, making the job much time-consuming.

The app also comes with a handy inch/cm converter.

Thank you again, Vikas, for your help with the installation.

After looking around at a few different size chart option I gave Ultimate Size Chart a go.

This app was exactly what I was looking for.

Would highly recommend this app to anyone who is seeking a size chart option for their site.

The app is very easy to use and the layout is fantastic.

Support for the app is awesome with Vikas being nothing short of sensational with the support that is given.

Awesome app for showing sizing charts, flexible and easy to customize. Best part is you can upload sizes via csv format to save heaps of time for a complex site with heaps of different products. Excellent support as well! Highly recommend!

Excellent App with even better support. Rare to see an app that does way more than we'll ever need! Looks great on the front end and a very robust backend app UI. A must have if you have lots of size charts.

Fantastic helpdesk! They helped me through every little obstacle i met.
It's pretty easy to add size charts to your products.
Totally would recommend this app!
