Sizes completely wrong

Clearly don’t update the app very regularly as your sizes are completely out depending on which phone you use, maybe you need to adjust this! Other ring sizing apps are more accurate so how come yours isn’t?

Very useful

Wanted to surprise the wife but didn't know ring size and this app worked very well to find her ring size accurately.

Really couldn't be bothered to go to a shop just to find ring size. Works great. Thank you!
