### 5/5 — Too 👍

*2026-08-02*

Very useful

### 1/5 — No slider

*2025-06-21*

It tells you to use the slider to find your size but I couldn’t find a slider. Useless.

### 1/5 — sizing

*2025-06-14*

sizing is completely off.

### 1/5 — Find another method

*2025-03-25*

I recently put a gold ring up for sale on ebay, and after making the sale, the ebay “authentication” department denied the sale due to incorrect sizing as specified in my ad. I used this app to size my ring—big mistake. Good thing this app is free, because it’s useless. DELETE.

### 1/5 — Don’t click free trial, it’s fraud

*2024-12-25*

Don’t trust the free trial, they will charge you immediately

### 5/5 — certeiro!

*2024-07-28*

acabei de dar a aliança para minha namorada, ela amou e serviu perfeitamente, comprei escondido e medi escondido também, tudo na surpresa kkkk aplicativo massa

### 5/5 — Ms

*2024-07-12*

Great

### 1/5 — money deduction

*2024-04-02*

I lost $7 because I accidentally pressed the download button. Please do not download.

**Developer response:** Thanks for your feedback. Basic functions of the app are free, and you can buy additional features

### 1/5 — Refund requests

*2024-03-11*

I canceled it as soon as the payment was made 
I would like to request a refund.

### 2/5 — Некорректные данные

*2023-09-15*

Неправильно измеряет, где-то на полразмера больше показывает

**Developer response:** Thanks for your feedback!
