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 size-related returns and improve the buying experience.

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.

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

Developer repliedWhile Fit Quiz was installed on your shop, 57% of all orders (in supported categories) were made after using the app and with the recommended size. Sales conversion with Fit Quiz was 233% higher than without it. You gained $14 in revenue for every $1 spent on Fit Quiz. Our pricing is fully transparent. Usage fees are clearly displayed when you activate the subscription, accept the terms in Shopify admin, and on the "Billing" page at any time after installation. There are no hidden fees. Usage charges only occur when a shopper uses Fit Quiz and adds the recommended size to their cart. You can view all such cases directly in the app at any time. The app functioned without any technical or other issues while it was installed. It's unfortunate you didn't check the analytics dashboard to see Fit Quiz's positive effect or reach out to us with any questions about pricing and usage fees. Nevertheless, we're glad that Fit Quiz had such a great impact on your business and will be happy to help should you decide to try it again. Show more

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 had to pay for something I no longer wanted. And quite frankly, I don’t care if I received orders through your app—if I have to give all my earnings back to you due to hidden costs, it’s simply not worth it. Your pricing has become unreasonably high. I also reached out to Shopify’s support team, provided them with all the necessary screenshots, and explained the situation. Even they agreed that your billing practice was unfair, but they couldn’t do much about it since it depends on you. I initially continued using your app because the prices were reasonable, and I was actually enjoying it. However, when I received that bill, I was shocked by the unexpected charges. So don’t try to twist the situation to make me look like the bad guy, and certainly don’t accuse me of "threatening" you. I have every right to leave a negative review if I am dissatisfied with the service. I’d like to continue this conversation and finish it here, as I have more important things to focus on than arguing with liars. My bill did not come to $20, as you keep claiming—it was significantly higher. I’ve already shown the full details to Shopify support, and they confirmed that they will take action on the matter. It’s unhelpful to focus on the way I’ve expressed my concerns when, in reality, my frustration is entirely justified. The costs increased beyond my expectations, and despite my desire to cancel, I still ended up having to pay an amount far higher than anticipated. It seems easy to point fingers elsewhere and repeat the same responses, but I am telling you clearly that my bill was much higher, and that is the issue at hand. I would appreciate a more honest and constructive response moving forward.

Developer repliedThis review is not made in good faith. You reached out to our customer support team demanding a refund (nearly a week after your monthly subscription was renewed), threatening to leave a bad review if we don't give the refund, and using foul language. 1. You provided a screenshot of the invoice with the $20 subscription charge – as per our pricing terms (that have not changed in the last 2 years). There is no record of any other charges – neither on the screenshots you shared, nor in our Shopify admin. 2. All our billing is done via Shopify Billing API and terms of the subscription must be approved by a shop, when subscribing. In your case, the subscription was activated and agreed upon 3 months ago, in December 2024. It's legally and technically not possible for us (or any app developer on Shopify) to change the prices, once you've activated the subscription. Hence the statement is contradictory: - you first mention: "I initially continued using your app because the prices were reasonable, and I was actually enjoying it' - and then "Your pricing has become unreasonably high" The pricing has not changed. It has been the same – not just for the 3 months you used the app but for the last 2 years. 3. When our customer support manager explained the charges and how Shopify Billing API works, you threatened a legal action (over a $20 subscription) and proceeded to repeatedly use foul language and insult the manager. At this point, the support manager closed the conversation. This all despite us offering to help you re-integrate the app (to use for the remainder of the paid subscription period) and the app functioning without any issues. 4. You used the app for 3 months and it had positive impact on the business: - 27% of your orders were made with the recommended size - the sales conversion was 241% higher with the recommended size 5. We work hard on improving our app but it is not OK to treat the customer support team in such way – we will not be tolerating conversation, where our team is insulted and cursed at. It is also not OK to demand a refund and threaten the team with a bad review. Show more

I’ve been using Fit Quiz for over a year now, and it has helped tremendously the way we handle sizing and fit for our customers. Recently, I encountered a minor issue where a button led to a "404 page not found" error, but it was quickly resolved. It’s a good feeling to know that behind a great product there's a support team that’s equally efficient. The monthly reports generated by Fit Quiz offers deep insights that help us understand our customers’ needs better. I can't recommend Fit Quiz highly enough for any retailer looking to improve their sizing accuracy and customer experience.

Awesome app, and even better customer service! They'll help you get anything to work right away. Using the app has reduced return rate for us, and even increases conversion rate when after visitors have taken the size quiz.

I've been a Fit Quiz customer for a long time, and our customers use it a lot. The app does its work very well! Alex helped us change to yearly billing, a significant improvement compared to usage billing. We will continue to expand our product range and integrate Fit Quiz!

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

Developer repliedThank you so much for your positive review! We strive to provide the best possible experience for our customers, and your feedback is invaluable to us. Show more
