‘Sizer’는 나의 옷의 사이즈를 저장하고, 이를 활용하여 쇼핑할 때 옷을 입어보지 않고도 옷의 사이즈를 비교하여 좀 더 편리하게 옷을 구매 할 수 있게 도와주는 앱입니다. ‘이쁘고 손이 많이 가는 바지의 치수를 저장하고 다음번에 인터넷 주문할 때 참고해야겠다’ ‘입어보기 귀찮은데 사이즈가 어떻게 되지? 내가 가지고 있는 옷이랑 비교해야지’ 나에게 맞는 예쁜 핏의 옷을 저장해주세요. 그리고 비교하여 구매하세요 또 비교하여 구매한 옷은 다시 나의 옷장으로 넣어주세요. 입어보지 않고 사이즈 비교만으로 쇼핑을 도와드립니다. Step 1. 나의 옷 사이즈 등록: SIzer에 자주 입는 옷들의 사이즈를 등록할 수 있습니다. 티셔츠, 바지 , 자켓, 원피스등의 8가지의 카테고리에서 나의 옷의 사이즈를 등록할 수 있습니다. Step 2. 옷 사이즈 비교: 쇼핑할 때, 사용자가 구매하려는 옷의 사이즈를 확인할 수 있습니다. ‘Sizer’는 등록된 사용자의 사이즈 정보와 쇼핑하려는 옷의 사이즈를 비교하여 얼마나 차이가 나는지 보여줍니다. 이를 통해 자신에게 가장 알맞은 옷 사이즈를 선택할 수 있습니다.

Verdict
The clearest difference is in-app purchases: Sizer at none against Converter Pro's 1. Converter Pro's advantage is device support and iOS requirement (18.0 vs 26.0). On price there is nothing between them.
