## What is Sizer?

SIZER БЫЛ НОМИНИРОВАН НА ЗВАНИЕ ЛУЧШЕГО ПРИЛОЖЕНИЯ В КАТЕГОРИИ LIFESTYLE 16-ОЙ ЕЖЕГОДНОЙ МЕЖДУНАРОДНОЙ ПРЕМИИ THE WEBBY AWARDS И СТАЛ APPLE APP OF THE WEEK

Sizer application can help you to choose the right size of clothes in the U.S., Europe, the U.K., Japan or Russia. All you need to know is one of the sizes — the application will tell the rest. Making a shopping trip to another country, online purchasing and an unexpected gift to your beloved will be easier when you can convert sizes on the go.

Why do we make Sizer?

Today there is no easy way to order clothes online and be sure that it will fit on you well. Size charts do not help, because the size varies and depends on the brand, season, style and region. Size is the reason for the return of 30% of purchased goods online.

Sizer is designed to solve this problem - a smart algorithm that learns based on user data:
1) be brave in online shopping;
2) forget about returns;
3) save shopping from stress.


How does Sizer work?

1. You select sizes with the help of our algorithm.
2. With the help of a button you give feedback - fit or didn’t fit.
3. Sizer teaches the sizing algorithm.

Shopping is no longer a lottery with Sizer.
