WAY too many ads and sizing is innacurate. Immediately upon opening the app for the first time, I was bombarded by 3 different ads, the first a pop up, then the 2 others just on the screen taking up 50% of the screen space. Move over to other tabs, more pop up ads. Won't even show you the ring size without a mandatory 60 second ad first, then come to find the sizer isn't even accurate. Tested it with an 8 1/2 sized ring I had, it said it was a 9 3/4. Do not bother with this app.

Size was pretty on, I guess, but they should show an example so people know how to line up the ring. It could be directly on the circle shown or allowing the circle to show slightly inside the provided ring. I did it allowing the ring provided show slightly inside mine, and it was 1/4 off. The finger measurement lol is a joke because people have different thicknesses of fingers. I would have rated higher if not for the ads. There is another app that is the same thing without constant ads.

I can't believe this app, it's awesome. My husband and could not for the life of us figure out what size our wedding rings were (it's been 33 yrs) and we looked online but the calculations in inches and mm didn't make sense. Within minutes of downloading this app we threw our rings on the adjustable sizer and there we had it. Thanks for creating this app. 👍👍
