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.

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.

It worked
Worked perfectly for me. Sized at 11 and got the ring which fit great.
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 ?
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.
Worst app ever
Followed instructions to the “t” no stop error messages. Don’t bother
Worked for me
This app worked well for me. It meant I didn’t need the sizing kit. Worked for both hands.
Doesn’t work at all
Took a dozen pictures exactly meeting the criteria. Error message every time. Just order the sizing kit.
Less accurate than guessing
After using this app over 20 times in a row in different light conditions, on different backgrounds, it has determined that my ring size is definitely either 7, 8, 9, or 10.
DOES NOT WORK
Don’t bother, doesn’t work!
