SmartSize is a user-friendly and intuitive app that's easy to use. The customer service is top-notch—Leslie and Elena always go above and beyond to answer questions, explain everything clearly, and resolve any issues quickly. Their support has been outstanding, making the overall experience seamless and enjoyable. I highly recommend SmartSize!

The App is simple to use, but powerful. We have only just implemented it, but I can see customers are already engaging with it and we are confident it will dramatically reduce returns - an important issue for a DTC online women's jeans brand! Customer support is genuinely excellent - I raised a query at 11am, received a response within a minute and was on a detailed discussion call an hour later. My query solved! Best size app I have found after months of research.

So far using the Size Chart, and it is amazing - clean and customizable. In process of setting up the size quiz, but so far looking very good compared to other similar apps we have tested.

Work on Smart Size Chart & Fit Finder?
Any amount puts this listing above the review-data order, on the board and in Selling products. Every amount and every click is printed in public. Paying also opens a private page for this listing – that is where the badge for your site, the share card and your deal live. Everything you can do here, including what money cannot buy and how to get this listing corrected or taken down.
Not ready to pay for anything? Take the badge – it shows this listing’s live rank on your own site, it is free, and it always was.
Claiming is free and it shows: the listing turns gold in every list – the same highlight a paid card carries – with a Claimed badge, in the exact place its reviews put it. It also earns the only followed link on this site: a claimed listing that has paid nothing links to its own website dofollow – a paid placement never does, because a link that was paid for is an ad. Claiming moves nothing.
