Really recommend both the app & the developer / support team behind it- we've used this for a number of years and we've been really impressed with how well the app works for us and how user friendly it is.

— Charlotte Mills

Amazing customer service. Julia is above and beyond. This is what is needed to keep apps alive. We can basically create most with AI now, but if the app is cheap and customisable, even with own vibe coding making it difficult, then I stay. And I stay. Most apps I delete now. Some are complicated and must wait, but this app is awesome for our complicated set up. Good job.

Customer service has been exceptional — Julia and the team are quick to respond and always proactive with suggestions. The app integrates cleanly into our custom Shopify theme without interfering with the design or performance. We've seen a genuine uptick in conversion since installing Fit Quiz and have just upgraded to the Premium plan. Highly recommend for any fashion brand looking to reduce siz...

We tested multiple sizing solutions, and Easysize stood out. Easy to implement, performs well, and the team is incredibly responsive and helpful. Highly recommend.

We have been using it for more than one year, it's very useful!

— Rifo S.r.l.

Easysize do not operate in good faith. Disappointed with how EasySize handles billing. We escalated beyond support and still got nowhere. For a tool aimed at Shopify businesses, the customer care around renewals is a real red flag. Would not recommend based on our experience. Save yourself and don’t touch this app. I've now seen other reviews relating to the same thing. Wish I saw this beforehand....

No support on weekend, expensive, not easy option for languages, much work to do.

— Yoana Sofia

omg. 15 cent per add to cart. i was billed so high for a month this is a scam

— BEEGLEE

Don’t use this app, is just a scam and terrible customer support . Let me explain in detail what happened because, apparently, I can't reply back(so i will include my answer here), and it’s unfair for you to make false claims. First of all, we are not talking about a $20 subscription—I received a much higher bill, which included unexpected expenses. Naturally, I was frustrated to find out that I...

Hij gaat alleen maar uit van de maat die je normaal draagt, als ik bij wijze van spreke 4XL invul en zeg dat ik 150cm ben geeft die alsnog aan dat mijn maat 3XL is... klopt niet en te duur voor wat je krijgt. ook de uitlijning van de tekst op je productpagina is niet handig en goed in te stellen...

*UPDATE REVIEW AFTER 2 YEARS USING* I had to remove my review, and initial stars. Before This app used to be beneficial, It did help out with customers. However, I've noticed over even the past year. you've been having a lot of issues that if we made even the slightest change to anything with our theme, the complete app would just disappear entirely. I wouldn't know about it, I wouldn't be notifie...
