I tried a few different size-chart apps and this was definitely the best one. Works well and looks great in my store. The only thing that I wish I could do is have two side-by-side links - one for size chart and one for a conversion chart. I have to have my conversion chart in a different place on the product page, which is fine but not ideal.

You can't have two links but you can have two size charts for the same product with the premium plan.

Good App for non-coders (i.e) someone who wants to set up charts easily. Having the link on our products needed a bit of customisation and support were very helpful with this.

I used this app to create a pop-up size chart specific to different collections. It was easy to set up and the results look professional. It would be better if you could copy and paste an entire table at once, but instead you have to type into every cell individually. However, once that is done, it looks great.

You will be happy to know you can copy and paste an entire table at once :)

Some browsers have issues with this, but you can scroll to the bottom of the size chart page and click on the rocket ship in the bottom left.

It looks like this...
