J’ai changé de couleur de fonds 4 fois, changé de carte, chaque fois cela ne fonctionne pas: ne voit pas ma carte, ne voit pas mes doigts. Bref, je ne réussi même pas à recevoir une suggestion de grandeur de bague. ### 1/5 — Ne fonctionne pas *2025-03-17* Testée dans tous les sens pourtant et des luminosités et des fonds différents, rien à faire -> retry ### 1/5 — Does not work at all *2025-01-27* Get there sizing kit don’t used this app don’t even work. All so when it did says size 6 that just my finger tip actually size is 12 ### 5/5 — Worked perfectly *2025-01-24* I used this app but ended up ordering the sizing kit just to be sure. The size the app told me was correct. ### 1/5 — Doesn’t work *2024-12-23* This app doe not work. It said it doesn’t recognize the two objects ### 5/5 — Worked great! *2024-12-17* 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. ## Frequently asked questions about Ultrahuman Ring Sizer ### What does the Ultrahuman Ring Sizer app do?
