Use the ring sizing app from 'Jason Withers'. It is SO much more user friendly. It gives you simple, clear and easy instructions to measure your ring size. You simply place a ring that fits your finger on the screen & slide to match the diameter of the ring, you will see highlighted on the table what size your ring is. It also gives you the sizes according to where you are located AU/GB, EU/ISO or JP/CN. I tried a few apps. And this one was the most easy, and accurate! Good luck!

Our app does exactly the same. In addition to that it can show your ring size without having a ring. Tell us, please, what was not clear in the instructions. We'd like to hear from you what was not as you thought it should be. looking forward hearing from you. Regards.

It's a really good app that let you know your ring's size but the problem is that when you swipe the screen to make the circle look bigger it doesn't work and keep making it be smaller It's impossible to know your ring's size if you have big fingers and all because of the swipe issue Fix that up

No way to adjust scale. Instructions at start are static and the scale is not available in the app
