### 1/5 — 😡😡

*2026-03-11, version 2.0.5*

### 5/5 — Great app

*2025-11-23*

I wanted to surprise my girlfriend with an engagement ring and had no idea how to get her size secretly. I used this app to measure one of her rings, and the one I bought fit perfectly.

**Developer response:** Thank you for your review. We're really glad the app helped you measure the ring size accurately and even more so that the surprise worked out. If you ever have suggestions to make the app even more helpful, feel free to let us know

### 5/5 — Spot on

*2025-11-16*

When I first began using this app, I double-checked the measurements at a jeweler, and they were spot on. It's a simple, brilliant tool that does exactly what it promises with clear instructions.

**Developer response:** Thank you for your review. We're glad to hear the measurements matched the jeweler’s and that the app felt clear and reliable to use. If you ever have ideas for improvements or additional features, we’d be happy to hear them.

### 5/5 — It’s good

*2025-11-14*

I wanted to surprise my girlfriend with an engagement ring and had no idea how to get her size secretly. I used this app to measure one of her rings, and the one I bought fit perfectly.

**Developer response:** Thank you for sharing your experience. We're happy to hear the app helped you find the right size and that your surprise worked out perfectly. If you have any suggestions to make the app even better, feel free to let us know.

### 5/5 — Multiple systems

*2025-11-14*

As someone who buys vintage rings from online markets all over the world, the different measurement systems that come with the app are extremely helpful. Say goodbye to those confusing charts or even guessing.

**Developer response:** Thank you for your review. We're glad the multiple sizing systems are making things easier for you, especially when buying vintage rings from different regions. If you ever have ideas for additional features or improvements, we’d love to hear them.

### 5/5 — No printing

*2025-11-13*

I used this app to sort through my grandmother's old jewelry box and could instantly tell which rings would fit me and my sisters. It's faster than digging out a physical sizer and more accurate than trying to print one out.

**Developer response:** Thank you for your review. We're glad the app helped you sort through the jewelry and find the right sizes quickly. If you have any suggestions that could make the experience even smoother, feel free to share them.

### 5/5 — Old ring

*2025-11-12*

I'll be honest, I was skeptical that this could work. I thought it was a gimmick. But I needed to check the size of an old ring for resizing and decided to try it, and I was shocked by how accurate it was.

**Developer response:** Thank you for your review. We're glad to hear the app exceeded your expectations and gave you an accurate measurement, even for an older ring. If you have any suggestions for future improvements, we’re always open to feedback.

### 1/5 — Scam

*2025-11-06*

Scam, they just try to get you to subscribe to a weekly fee… like I need to measure a ring every week… completely uses less and misleading

**Developer response:** Thank you for your feedback. We understand the frustration with seeing a subscription offer right away. The app does include free tools that can be used without subscribing, though some advanced features are paid.
For most users, measuring a ring is an occasional task, and you can do that with the free content. The subscription is optional and meant for those who want ongoing premium features.
Thank you for sharing your concerns, your feedback helps us improve how this is presented.

### 1/5 — Incredibly inaccurate

*2025-09-03, version 2.0.3*

The sizes are WAY off. I tried it with my ring on the screen as prompted so i can order some other rings online and the size this app gave me it s like 4 size larger than what I have 😂 unreal

### 1/5 — Not accurate

*2025-06-28, version 2.0.1*

Not accurate, not easy to use. It gets worse. They write that you have a trial just as language and still charge you. So I paid for this unwillingly and never figured out my ring size. nothing worked. It was awful.
