## Ultrahuman Ring Sizer Reviews in United States

### ***** "Worked great!"
I had already bought a sizing kit from Walmart so I knew my size but came across this and wanted to try it. I did both hands using a black credit card and a white piece of paper. I did my right hand first, it was pretty quick, then did my left hand which took a bit longer, but both sized to a 9 which was exactly what I wore from the sizing kit on both hands! It does work but takes patience to turn the cross hairs green then hold still to take the picture.
-- NuMe18, 2024-12-17

### *---- "Does not work"
What the title says
-- LC555555, 2024-12-11

### *---- "Does not work"
In my opinion, this app is frustrating and it’s a piece of trash. I changed the color of the credit card. I changed the color of the background. I use the right hand. I use the left hand. I did everything I was supposed to do and each time it told me either there was too much noise in the background or it told me the background was too dark or it told me it couldn’t detect both items whatever in the world that means it didn’t work at all for me. I would not recommend this app at all.
-- ACPKSMS, 2024-10-03

### ***** "Accurate if done properly"
This sizer works great IF you follow directions and do it correctly. I found that if I did not center my middle finger with the card I was using or if I had the camera too far away from the hand when taking the photo, the reading would not work properly. I did around 6 readings for each hand and it would vary between size 7 and 8, with most of the time saying it was a 7 or a 7 with alternative of 8. I was worried it wasn’t going to work well but when I got my size 7 ring, it fit perfectly.
-- Zuzu1069, 2024-07-02

### ***** "It worked"
Worked perfectly for me. Sized at 11 and got the ring which fit great.
-- Jljljljl454545, 2024-06-23

### *---- "Horrible"
Gave me a size that’s 2 sizes smaller. Tested with the ring sizing kit by Ultrahuman. Being in tech myself, needs a lot of work and shouldn’t even be on the AppStore as of now. Also reflects about whether Ultrahuman is doing such early buggy releases with their activity tracking models as well ?
-- hrishikesh_saraf, 2024-06-19

### *---- "Junk"
Took over 2 dozen photos; all of the meeting the requirements and with different backgrounds and different cards. Never got it to work. Just order the sizing kit on Amazon. It's $1 here in the US.
-- AndroiDoughBoy, 2024-05-31

### *---- "Worst app ever"
Followed instructions to the “t” no stop error messages. Don’t bother
-- Mermaid Rebel, 2024-04-06

### *---- "Doesn’t work at all"
Took a dozen pictures exactly meeting the criteria. Error message every time. Just order the sizing kit.
-- J. Stout, 2024-02-24

### *---- "DOES NOT WORK"
Don’t bother, doesn’t work!
-- lanb61, 2024-02-15

### *---- "Completely wrong size"
I was going to order a sizing kit but it was going to be 2-4 weeks to get here. I opted for the app. The app said I was a 6. Ordered the rind from Amazon  and 2 day later and it did not fit over my knuckle. It only for my pinky. The is app is horrible. I recommend the kit. The shop time need to better fore the kit. I ordered the kit and I am returning the ring I got and will have to wait to reorder for the right size.
-- LekaLeka, 2024-01-13

### *---- "Ended up with the wrong size ring"
Now I have to go through the hassle of exchanging it, which is going to take weeks. Don't use this app, get a good size elsewhere.
-- Kleenex4u, 2024-01-11

### ***-- "It works.. but do the physical sizing kit if you can wait"
Same as the another reviewer did not want to wait for the sizing kit. Getting the app to spit out sizing is a hit or miss but was able to get sizing a few times (7s and 8s). I went with the 8 and it fits my ring finger well but too tight for my index finger where I was planning to use it on. It would be nice if they can do estimates for all fingers instead of picking 1 or 2 per try..
-- lzone101, 2024-01-09

### *---- "Doesn’t work well"
Same as others. Many attempts, but either can’t detect my fingers or can’t detect the card.
-- Shelaba, 2023-12-28

### ****- "Worked well"
I didn’t want to wait for a sizing kit before ordering my ring so I thought this app would be worth a try. I want to wear my ring on my right (dominate) hand, so I needed to hold the camera in my left hand which was a little awkward. I took the test 6 times and got variable results. An 8, 9, 10 (3 times), and an 11. So I went with the 10 and it fits perfectly. So I would just recommend doing several tests.
-- Quickjd, 2023-12-12

### *---- "Doesn’t work"
Tried several cards. Tried several ways of positioning my hand and the card. Would never work.
-- Vicarius89, 2023-11-21

### *---- "Doesn’t work"
Tried at least 15 times and could never detect the card. Tried different cards and surfaces, no matter what I tried it didn’t work.
-- Ddddaaave, 2023-11-18

### *---- "Recommended a size 9 when I’m easily a 12. Oura size 13 didn’t fit the same finger."
Not sure what the sizer app is doing. Hopefully not indicative of the rest of the app suite.
-- ChangLegacy, 2023-11-17
