I never write reviews

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 😂

Terrific App!

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 😊


App doesn’t work at all

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.
