User Reviews

Users broadly complain that the app is overwhelmed by ads, which disrupts the sizing flow and even freezes the screen. Sizing results are repeatedly described as inaccurate or inconsistent, sometimes wildly so. A few note it once worked well, but the current experience is dominated by ad-driven usage and intrusive review prompts. Overall, usability and accuracy are the main issues, making it unreliable as a ring-size tool.

Pros

Uses a simple finger-sizing chart for quick sizing.
Historically reported to work flawlessly when not affected by ads.
The app is designed specifically for ring sizing and provides a size result when accessible.

Cons

Excessive, unskippable ads that interrupt usage.
Ring sizing results are often inaccurate or inconsistent across fingers.
Ads frequently freeze or block the screen, making the app nearly unusable.
Intrusive, frequent prompts to leave reviews disrupt usage.
Some devices report extreme mis-sizing or incorrect measurements (sizes vastly off on certain devices).

Not even remotely accurate

You are bombarded with advertising and they want you to put your finger on the screen to measure in the meantime you will get 10 ads before you can even do that. Once you get past that it helps you get an idea of your ring size.
