Worked like a charm!!!

I bought a ring to give as a gift, and I wasn’t sure if it was the right size. (I bought it from a third seller) This app was just what I needed!

The worst

I used this to get my ring size. It measured 7. I was a bit skeptical cause my hands/fingers are small. When I got my actual ring, it was 3 sizes too big. Had to send the ring back for 5.5.

Developer Response ,

Verify that you have used the correct measurement system. The app use are sizes for both US/CA and JP/CN. Both systems use a digital designation, but if in America the size of the ring is 4, then in Japan the same ring will already have size 7.
