### 2/5 — Wrong size by Far

*2021-12-11*

It says my ring is size 4-1/2…but it’s a 7 USA. I checked most of the countries & those numbers are even worse. Would like an accurate app suggestion.

### 1/5 — Crashed

*2020-05-01*

Constantly crashed and was unusable

### 1/5 — Doesn’t work

*2019-12-13*

I downloaded the app and it doesn’t even open. Doesn’t even deserve the 1 star

### 1/5 — Worthless App

*2019-12-03*

This app crashes when very time you open it. Waste of time

### 5/5 — Accurate and easy

*2019-09-17*

I have downloaded hundreds of ring sizers and this is by far the best. 10 stars!

### 1/5 — This is not accurate!

*2018-12-12*

It said my wedding band was 10. It is a 6.5.

### 5/5 — This app is great!

*2018-05-31*

Used this app to determine the size of a ring that belonged to my grandmother and it fits me!

### 5/5 — This sizer works!

*2018-05-27*

Going to buy my husband a new wedding ring as a surprise for our anniversary. Used his old ring as a model with the app. The new ring fits perfectly and he lives it.

### 5/5 — International Ring Sizer

*2018-04-30*

**Developer response:** That’s great news! Glad to hear this app worked perfectly for your needs!
