About this app

The Ring Sizer by Jason Withers app solves the problem of determining the correct ring size, which is particularly useful for individuals planning to propose or purchase engagement and wedding rings. Despite its utility, the app falls short with a below-average user rating of 2.4/5, indicating significant issues that may deter potential users. In comparison to other lifestyle apps, Ring Sizer's simplicity and lack of comprehensive features may make it less appealing. However, its large user base of over 5 million downloads suggests that it still maintains a level of relevance and usefulness.

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.
