Then when I reran it since I know it was wrong, it made me wait for 3 ads then didn’t get a result. ### 1/5 — Trash App! *2026-07-12, version 4.0.5* Save your patience and time and avoid this absolute garbage of an po. It’s littered with ads ranging from penis enlargement to Temu. It will try and track and extract any and all information from you it can to sell to Ching Chong overseas. ### 1/5 — inaccurate *2026-07-08, version 4.0.5* measured a size 6.5 ring and it said 9.75 ### 1/5 — Not even close *2026-07-07, version 4.0.5* Tried this against known rings and finger sizes. None of the measurements were accurate. ### 1/5 — Useless *2026-07-04* The app doesn’t work. They force you to watch two very long adverts but, after that, the “exit” button won’t work. You might try to do everything again, and it won’t work again. Installed, tried out and deleted. ### 2/5 — Never got past the ad screen *2026-07-03, version 4.0.5* I have no objections to ads for free apps but this one not only had click bait (…out of date. Click here to update), it never got past the ad screen. So I was never even able to use the app ### 1/5 — Awful *2026-07-01, version 4.0.5* Some ad is expected, but the amount of ad in the app is crazy unreasonable and completely annoying ### 3/5 — Used to be amazing *2026-06-30, version 4.0.5* The app used to be my go-to but now it’s impossible to use! Too many ads and it’s super annoying! I preferred the older version / interface, easy and smooth! I wish there’s a way to download the old version I regret updating the app! Other than that, there’s potential to be the best out there! ### 1/5 — AD Fuel Nightmare *2026-06-27, version 4.0.5* Not really accurate and way too many ads. Just avoid. ### 1/5 — Not even remotely accurate *2026-06-16, version 4.0.5* Not even remotely accurate ### 2/5 — Frustrating to use App *2026-06-10, version 4.0.5* 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. ### 2/5 — Gives wrong measurement on iPhone 13 mini *2026-05-31* Use to be good until I found out there is a difference between the announced diameter on the app and the real diameter I mesure with good mesure tools…. ### 1/5 — Inaccurate at sizing *2026-05-25, version 4.0.5* Completely inaccurate by at least 2 sizes. Measured at the innermost edge of the inside of the ring and it was still registering 2 sizes larger. ### 1/5 — Useless *2026-05-11, version 4.0.5* Just another useless ad app that asks for inappropriate access to phone resources that it shouldn’t! ### 1/5 — Not working at all *2026-05-07, version 4.0.5* Not working at all ### 1/5 — promotes scams *2026-05-07, version 4.0.5* this app with forcefully present ads that imply the users’ device has been compromised. unethical to say the least, and the devs/marketing teams should be ashamed of themselves for allowing such nonsense. ### 1/5 — Muito ruim *2026-04-18* Uma quantidade absurda de anúncio pra um app com uma única função ### 1/5 — Deleted *2026-04-18, version 4.0.5* Deleted within minutes of downloading, full of adverts ## Most critical reviews (10 lowest-rated) ### 1/5 — Be wary *2026-08-25, version 4.0.6* No way to cancel subscription from app. ### 1/5 — Useless *2026-08-21, version 4.0.6* Can’t do a single thing without paying. Ridiculous concept ### 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 ### 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. ## Most praised reviews (10 highest-rated) ### 5/5 — Good *2026-03-14* Bom ### 5/5 — Good *2026-03-13, version 4.0.5* It’s good but I hate the ads ### 5/5 — Excellent *2026-01-22, version 4.0.5* Ok ### 5/5 — Ring sizer *2025-03-20* Cant use now all adds and pop ups useless ### 5/5 — Perfeito! *2025-01-16* Deu certinho, podem confiar! ### 5/5 — Iphone 16 problem *2025-01-10, version 4.0.5* I test this application in iphone 12-13-14-and iPhone x In all this phone the application is correct 100% But i use it in iphone 16 pro max The application is so much wrong And it is so much harmed me I wish the creator of this app Researching abut my problem In iphone 16 pro max ### 5/5 — Very helpful *2024-07-28, version 4.0.5* Very helpful!!!! ### 5/5 — Useful tool! *2024-07-24* Very useful for the customers. ### 5/5 — No good *2024-04-19, version 4.0.4* This was my absolute go to for years it’s sad that it’s completely rubbish now. As far as I can see it’s just ad after ad after ad. No longer shows the letter sizing only the number. I’m gutted it’s just so bad now. It was such a great tool now it’s been deleted… ### 5/5 — Surprisingly accurate! *2024-03-29* I’m a the start of my ring search. Went into a shop and was told to get a 3.5 but it felt so snug! Like terrified that it was stuck on my finger in the store snug. Another said the same, stating a 4 would be to big. This app confirmed quarter sizes and measured me a 3.75. It was a good feeling to be validated at the very least. Going to follow my gut and this app and get the quarter size up. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
