The Diamond Store Ring Sizer

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?

Compared to measurements it’s completely out! Ring is most likely k1/2 and app says m! (UK)

Depending on phone, there is a huge difference. iPhone XS Max gives size N, iPhone XR gives size V

Compared with different phones and the results are inconsistent - iPhone 11 Pro tells me it’s size H, whereby an iPhone 7 indicates it’s size K. Having used various other methods to measure the ring, I know it’s neither H, nor K.

It's completely wrong!

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

Ring had to be returned for MUCH smaller size. Don't use this ap, it's nowhere even close to being correct!

Not a true scale at all way way out ..... thankfully the app was free

This app is about as much use as a chocolate teapot!

The white circle was so tiny that you couldn't even size a baby ring.
