1.Use a flexible measuring tape or length of string. Wrap it around the finger you'll wear your ring on - if you're creating a ring stack, consider where on your finger the ring will sit. If using string, mark the point on the string where the ends meet with a pen.
2.Lay the string on a flat surface and use a ruler to measure the length (in inches or millimeters) up to the mark. Compare your measurement to the size chart above to determine your ring size. If you are between sizes, opt for the larger size.
A helpful method if you're surprising someone with a gift or treating yourself.

Enjoying the feedback, daily optimizing
I am so excited to get this sporty ring😆
The Great Experience will start.🎉
really impressed with the design and comfort. I love how it combines sporty energy with a premium look—definitely stands out from regular accessories.
I'm so happy to get the ring I've been waiting for. I'm working out by wearing it together every day now. It's fun to check your health and raise your gym points.
I saw the project in May, decided to take a risk and bought a pionet package.
The wait was tiring, as they promised to send the rings in July. However, they sent them in mid-August, I received the ring on August 29, I missed only 2 days of the mini season - this is not critical.
Overall, the product is high-quality, the motivation to keep myself in good shape has increased, especially if there is financial motivation, it is not the main one - but it is nice.
I wish the project good luck, I see prospects.
I get extra points. I'm happy with that. If we could choose the color of the extra rubber band, It would be perfect.
Ok
I like the ring.Wish It were a size bigger. It’s hard to take on and off
001,002,sporty ring...
best is 002.
I like simple design.
And very confortable fit for me.
I forgot that I wearing 002.
It's a great product. Nice app. I really appreciate the features. Battery life is crazy good.
Issues
I had one connection issue where I needed to reset the app. Also, the AI doesn't have access to my data. Finally, it would be nice if there was a tactile bump onboth sides of the ring to help identify where the sensors are, so I can ensure they're in the best position.
Overall, very happy with the purchase and I hope it lasts a long time!
Works seamlessly,connectivity great.Still testing,but so far good ,durable product with excellent battery life.The no subscription model is one of the things that stands out about this ring and CUDIS project.
great design
