This app is amazing and really helpful. It makes working out your ring size super easy and quick, all from your smartphone. It's been a lifesaver for me, especially when I can't find my metal measurement tool. I was surprised to see some negative reviews because it's a free app that gives accurate measurements and doesn't take up much storage space. It's definitely worthy of a five-star rating!

I laid the ring on the grid and started tapping room sizes to increase the circle size to match the inside of the ring I was sizing. After increasing the size 4 or 5 times an ad popped up, which I couldn't figure out how to close. So, I closed the app, reopened it, tapped a ring size, got an ad. After close, open, tap, ad a few times, I reinstalled the app and again, after 4 or 5 taps, an ad popped up. Then, close, open, tap, ad, close, open, tap, ad, close, open, tap, ad. You get the point.

Dear user, Thanks for supporting us and we are sorry for Ads. Alternatively you can try the measurement ruler slider in the screen, that should not cause you this problem. We will improve in the future and we will try to keep the Ads from interfering. Please let us know if you have any questions. Thank you.

HORRIBLE! You cannot even make it through the video tutorial of how to use the app because an add pops up then you have to start the tutorial over but another add pops up again. Unusable if you can't even watch the tutorial video. Have you all even tried to use your own app?
