Seems accurate

I wanted to two my kids what size for a mother’s ring. I think the app should clarify where the circle should line up with your ring. Inner circle? Directly under ring? Outer circle? A 1/4 inch is easy to misjudge. If I use inner circle whereas I can barely see the circle (where my finger goes, right?).. I’m a 6. Directly under I’m a 6 1/4... outer 6.5.
I think I’m a 6 🤷🏼‍♀️

Developer Response ,

Yes, you should measure using the inner circle. Use guides for more accurate measurement. And thank you for your review!

Amazing app & amazing accuracy

I was looking to convert my US size to a EU. This app is so simple and intuitive. You can even measure the size of a ring you own on the screen. It also has a chart to that shows the different cuts of stones and setting names. So much more than what I needed! Thank you!
