### 1/5 — AD city

*2026-08-11, version 4.0.5*

Don’t download this the measurements aren’t right and it’s just full of ads

### 1/5 — Too many ads

*2026-08-08, version 4.0.5*

I tried using this app and every single time you click to do something it generates ads. They aren’t the quick ones either. Too frustrating.

### 1/5 — Ads, ads, and more ads

*2026-08-07, version 4.0.5*

Just a Trojan horse of ad hell, impossible to actually get to the promised service.

### 1/5 — Full of advertising

*2026-08-01*

Not even one star

### 1/5 — HORRIBLE

*2026-07-31, version 4.0.5*

size not accurate when you use your finger. You have to use a actual ring for accuracy which makes it pointless almost. And a add pops up EVERY SINGLE TIME you try to get your size information.

### 1/5 — Not completely accurate

*2026-07-26, version 4.0.5*

I used the app, placed my ring that I’m already wearing on it, followed the instructions to a t and it said my ring size was 10. I didn’t think it was a ten, so I went by my local Walmart, asked for their ring checker thing, checked it and it was NOT 10. It was 7. Just make sure you go get it checked if your needing it for important reasons, hope this helps someone

### 1/5 — Funktioniert wegen Werbung nicht

*2026-07-26*

Wenn man die Größe angucken will kommt Werbung die nicht weiter geht und man bleibt in der Werbung hängen

### 3/5 — Works great but..

*2026-07-24, version 4.0.5*

Having to wait for 2 ads to play before getting your answer is annoying.

### 1/5 — Ads galore!!

*2026-07-23, version 4.0.5*

If you are interested in ads and not ring sizes, then this is the app for you!! within the first two minutes of downloading, I was able to assess my finger size but in order to get the ring size I had to watch three different ads. don’t bother.

### 1/5 — It’s not accurate

*2026-07-20, version 4.0.5*

It gave me two completely different answers for the ring one and the finger one.
