Best size app out there hands down! I love the size recommender feature, it's a feature you see on big sites and this app makes that technology available for us too! Love it, keep it up!


Swimming Apparel

I have wanted an app like this for my online store for over 10 years! This is fantastic, it is very intuitive and easy to create custom size charts that customers can even find out their size...


Lingerie Fashion

...I have a store with 300+ dresses, most with different sizing, so I just made one beautiful template & applied it to all the dresses. It's been a lot easier than I anticipated for a store with that many size charts.


Women Apparel

For an entire year - we have had such major issues with sizing charts...because we were having high return rate, too many emails about sizing chart confusion, and high exchange rate....Found this app and it hit the nail in every aspect of what I'm needing... including dynamic sizing suggestions...
