YOUR(FRËÀK)GURL review for Smart Size Chart & Fit Finder

I used this app to help create a size chart for my ecommerce website. The difficult part that I found was connecting the site to my specific theme settings, which needed me to go into the product page and code it myself. However, I struggle with this and needed assistance. It would be great if this process was avoided to create a quicker turn around and didn't need coding to be applied.
