Surprisingly accurate!
I’m a the start of my ring search. Went into a shop and was told to get a 3.5 but it felt so snug! Like terrified that it was stuck on my finger in the store snug. Another said the same, stating a 4 would be to big. This app confirmed quarter sizes and measured me a 3.75. It was a good feeling to be validated at the very least. Going to follow my gut and this app and get the quarter size up.

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 🤷🏼‍♀️

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!

Easy and simple
Very useful app. I was unsure of the size of the ring and needed to order it right away, it really helped me to make sure I was ordering the correct size. It also has a convertion to europan and japanese sizes. I did not need but I believe it help other people that need this info.

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!

Directions would be helpful
The only thing I would suggest is to add directions to clarify understanding for people that are not familiar with ring sizing. Ex. Make sure the circle is just on the inside of the ring rather than in line with the ring.

Doesn’t work
My wedding ring is too small and I need a size up, but I don’t know what size my wedding ring is. I sized it up based on the instructions given and sizes 7-8.5 was basically all measuring the same as my wedding ring. Not an accurate app at all and do not recommend buying a ring based on these measurements.

The information is not accurate and I don’t like being required to sit through ads only to discover that the sizing is wrong. Glad I didn’t pay for this.

Something is wrong
The tiny box with the circle in it is smaller than my ring. No way to open it up and use it.

App is no longer practical.
I’ve used it years ago but now the sizer is in a small window that doesn’t accommodate sizing. It’s become virtually useless.

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.

The circle for measuring is too small and as you increase its size, it runs outside the box and is not visible. Good app for small children’s size, but not adults.

Can’t size anything.
The measuring part of the app is too small and cannot measure any ring for any average adult. Was let down.

Very handy
This is a really cool ring sizer app. It's very easy to use. I checked it with a ring that I knew the size and the App was right on the mark. I have so many rings that I don't know the size of, so this will be very helpful tool. 👍

Master Jeweler loves app
Great app very accurate measuring. I am a Master Jeweler and this is great to use when a guy needs her ring size and wants to surprise her. He can do it from her other ring and call text or email us the size. Lady Jeweler, Ocala Florida

As advertised.
I've often wondered what ring size I am. Saw on television that there is an app that will tell you. Looked it up, downloaded it, took a ring that fit perfect and I wear a "6.5"! GREAT!

Ultimately worthless
Unless it's updated to account for different size displays, or offered a calibration feature, it's pointless. It consistently measured a size 2-3 sizes below my actual size on an iPhone 6+. Unless you measure the displayed diameter with a ruler/tape and get a match, then this app is useless. If I have a ruler/tape handy, then why would I need the app. Don't waste the memory on this POS.

Only works if your screen is “regular” sized!
Checked this on my samsung note 9 and on my ipad 5th generation. On the note 9, This device has a big 6.4 inch screen it seems off by 1.5 mm, the ruler says 21.5 while the app says 19.9. on ipad 5th generation 9.7 inch screen, It looks like the app doesn’t have a way to calibrate the size of the device display to accurately measure… also on the ipad there are 2 views minimized and maximized and changing between the two doesnt change the measurement… in the minimized view it was off by 5 mm while in max screen view it was about 15 mm off, showing a size 19.96 mm while the ruler says 35 mm!! It looks like the app was designed to work for phones with screen sizes ranging from 5.8 to 6.1 …if more or less the measurment could be way off. A solution is to put an option for size calibration
