I just downloaded this app after taking the whole weekend to try to create a brand aligned size chart for my store. I did have a question that was very quickly answered! My only complaint is that I did not find this app yesterday! Thank you so much!!! It is very easy to use and looks amazing on my store!

Really easy to use app and I was enjoying installing it but couldn't get the functionality I was looking for - the support team responded instantly to try and help me resolve. Ultimately the app couldn't do what I was looking for but then they pointed me to their partner app which can. Really really helpful and such a useful outcome. Thank you so much!
