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 😊

Ring size

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
