It gives the same result for every finger, and every finger of every member of the family. The result remains the same regardless of which ever finger is placed between the lines. ### 1/5 — Not accurate *2022-01-29, version 1.0.4* I kept getting the same reading and thought it was right but my actual size is 2 sizes bigger than the app told me. Definitely would recommend trying other methods and not this app. ### 1/5 — App doesn’t work at all *2021-10-16, version 1.0.4* I was going through the process and the app gave the instruction to gently place my finger on the screen. At this point I removed all rings and gently placed my finger at the bottom of the screen as instructed and nothing happened. The video stated it would show 2 parallel lines to then narrow it down to the widest part of the screen but nothing popped up. I was stuck on this screen and no matter how many times I lifted and placed my finger nothing happened. I tried to life the phone to trigger the warning that the phone wasn’t level then place it back down and that didn’t work either. Very frustrating that this app doesn’t work. ### 2/5 — Inaccurate *2021-10-07, version 1.0.4* Told me the wrong size, luckily I didn’t take the apps word for it. ### 1/5 — Just go to a jeweler *2021-07-12, version 1.0.4* I know my ring size.. but you have to wonder if this could be helpful in keeping up to date since your last jewelry purchase, so I downloaded and followed instructions and it’s way way off. It’s a whole 3 1/2 sizes off. This could be helpful but it needs improvements. ### 1/5 — Horribly Inaccurate - 2 sizes too small *2021-06-02, version 1.0.4* I know it’s inconvenient, but just go to a jewelry store and get properly sized. I used this app and very carefully followed the instructions and got a very consistent 8. My ring came and was way too small, so I went and got sized at a jewelry store, turns out I’m a 10. Just hoping they’ll fix or replace the ring since I spent a stupid amount of money on it and it was their stupid app that messed it up. ### 1/5 — It didn't work for me *2021-01-06, version 1.0.4* I went by the app because I genuinely had no idea about my ring size and didn't have any other way of measuring it. My ring was too big... and definitely way bigger than i expected it would be ### 1/5 — Needs work *2020-03-03, version 1.0.2* Didn’t get the right finger size, sometimes sends me to the main menu for no reason ### 1/5 — Garbage *2020-02-17, version 1.0.2* I would give zero stars if I could because the thing makes you download it size your finger then brings you back to the main screen no information given. ### 1/5 — Completely Unreliable *2019-10-26, version 1.0.2* Tried it many times and still came out completely wrong. ### 1/5 — Iphone XMax *2019-09-04, version 1.0.1* Every time I place a finger in the location, the phone thinks I’m trying to close the app. Couldn’t place my finger to properly size ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken *2026-03-20, version 1.2.2* App is broken and does not work. ### 1/5 — Confused *2026-01-16, version 1.2.2* I got 4 different sizes each time 🫩 5.0, 5.5, 6.5 n then 6.0 ### 1/5 — Will not load *2025-03-27, version 1.2.2* I have deleted and redownloaded twice, I have tried to download on my husbands android and still get the same message “something went wrong”. ### 1/5 — Hilariously inaccurate *2025-03-20, version 1.2.2* Followed instructions to the letter- it said my ring size is a 10.5 as I sit here in my 7.5 ring 😂 I have been measured at a jeweler- wildly incorrect. ### 1/5 — Doesn’t Work for iPhone 16 *2025-03-18, version 1.2.2* Downloaded app and when I go to open it, it says that it doesn’t recognize device ppi. App doesn’t work at all for iPhone 16, but it worked on iPhone 13. ### 1/5 — Doesn’t work *2024-10-29, version 1.2.2* I used my ring size I know for reference and it is definitely not accurate ### 1/5 — SCAM APPLE FLAG THIS APP *2023-04-27, version 1.0.4* This is a scam. When you download it and try to begin, it makes you watch video after video of adds to gain That is literally all so sorry, you cannot enter the app ### 1/5 — Saved me 2,500 dollars lol *2023-02-26, version 1.0.4* I’m a graduating senior at my university, and attempting to use this bad app really gave me time to think should I really keep trying to figure this app out and waste 2,500 dollars for a ring that everyone else in the university will get. Or should I instead go and buy something more meaning full and unique instead of a common ring. So again thanks to this app I saved my big bucks lol. ### 1/5 — Lies *2022-11-28, version 1.0.4* Does nothing, each time I tried it , it says my finger size is 0. I have tried it countless times, and I am definitely doing it right ### 1/5 — don’t download *2022-08-13, version 1.0.4* stupid app. didn’t even get past the 3rd step. ## Most praised reviews (10 highest-rated) ### 5/5 — Works great! *2023-04-23, version 1.0.4* If you follow the instructions (set the phone down on a flat surface, use one eye to measure) it works perfectly! ### 5/5 — Ring size *2022-10-20, version 1.0.4* This app was spot on I was in shock for real definitely would recommend ### 5/5 — Terrific App! *2020-10-06, version 1.0.3* I don’t wear a lot of jewelry but came across this gorgeous ring that I just had to have. Unfortunately, I didn’t remember my finger sizes and was freakin out because the ring was on sale 75% off for 1day only. Thanks to this app, I was able to order my ring and the sizing was spot on. Definitely a must have 😊 ### 5/5 — It does work *2020-08-07, version 1.0.2* It works I just got a ring that the app sized me for today and it fit perfectly ### 5/5 — Ring size *2020-08-03, version 1.0.2* Very accurate. I couldn’t remember exactly what my ring size was but once I followed the instructions I was able to confirm. Easy to follow too ### 5/5 — I never write reviews *2020-02-07, version 1.0.2* Ok so I ordered an OURA Ring the other day. I didn’t know my ring size, so I had to order the sizing kit as well. I tried on multiple ring sizes and found that a size 12 fits best on my middle finger. I stumbled on this app today and figured I’d test it out to see if it was accurate or not. Super easy to use, and it showed I was a size 12 on my ring finger. I’m actually really freakin impressed. Oh and it recommends you do it a few times to be sure... but it was spot-on accurate on the first try. To anyone that says they kept getting the wrong size after using this app... you my friend... are an idiot 😂 ### 5/5 — Great App *2019-09-27, version 1.0.2* Works great on iPhone X ### 5/5 — Got my size right the first time *2019-08-02, version 1.0* Extremely intuitive and useful. Game changer and something other companies aren’t doing ### 2/5 — Great concept, but… *2022-11-25, version 1.0.4* Decided to give this a try and order a ring online. The ring ended up so loose that I had to wear it on my thumb instead of my FY finger. It’s still loose on my thumb. You are better off buying a ring sizer and mandrill online for $10. ### 2/5 — Inaccurate *2022-04-14* Great idea/tech, terribly inaccurate --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
