About SMS | Apparel Size Recommender


Imagine your customer. Sitting at home on the couch with a tablet. Or on the train on the way home from work. Your customer scrolls through the internet and stumbles upon your store. You might even paid expensive ads so he sees you. You got the customers’ attention and he ends up clicking through your products. He wants to order but is unsure about sizing and clicks your sizing offer.

What will he find? An overwhelming size chart with a variety of options, sizes and ways to measure himself?

Do you think he will have a measuring tape with him on the train?

Do you think he will be willing to stand up from the couch to measure himself?

You just lost a potential customer.

Or worse: You won a potential multi-returner. Ordering different sizes of the same Tee only to return you all of them in the worst case.

We help you to prevent such stories and make exactly this customer purchase your products.

awesome App! love the functions. With other Apps users have to measure themselves to get results. So annoying. Here they just answer some questions and that's it. Dude, it rocks! Best Sizing App ever.

Size Recommendations work great. It's exactly what I was searching for! Takes a little patience to set it up because there are a lot of options - but hey, in the end it's worth it. Also, their support is just great! Thanks guys.
