Father & Daughter
Find Your Perfect Ring Size
Choosing the correct ring size is quick and easy. Follow the simple steps below to measure your finger accurately from home and find the best fit before placing your order.
How to Measure Your Ring Size
Fit
Make sure it fits comfortably. It should be snug, but not too tight, and should slide over your knuckle.
Mark
Mark the point where the two ends meet or overlap using a pen or pencil.
Measure
Lay it flat and measure the distance from the starting point to the mark in millimeters. Repeat 2–3 times.
Tips for Best Accuracy
Timing Matters
Measure your finger at the end of the day, when it is naturally slightly larger.
Avoid Cold Hands
Do not measure when your hands are cold, as fingers may temporarily become smaller.
Between Sizes?
If your measurement falls between two sizes, choose the larger size for a more comfortable fit.

Which finger should I wear my smart ring on?
The best spot is the index finger of your non-dominant hand. It gives the most accurate readings and comfort. The middle or ring finger also works well — just avoid the thumb or pinky for less reliable tracking.
What phones are compatible?
Our smart jewelry works with most modern smartphones — any Android device running version 5.1 or higher and iPhones with iOS 10.0 or later.
Just connect through the companion app via Bluetooth 5.0 or newer, and you’re ready to go.
What can the ring track?
The smart ring monitors your heart rate, blood oxygen (SpO₂), sleep quality, steps, calories, distance, and stress levels (HRV) .
It also supports multiple sport and workout modes, helping you track your activity and recovery throughout the day.
Some features may vary slightly depending on the model.
What materials are used?
Most of our smart rings are made with a stainless-steel shell and a hypoallergenic finish, with internal electronics fully sealed and sweatproof.
You can find detailed material information in the product description on each item’s page.
When Will I Get My Order?
All orders are usually shipped within 1–3 business days, and you’ll receive a confirmation email with tracking details once your package is on its way.
On average, it takes 5–8 business days for your jewelry to arrive from the time you place your order.
What if I don’t like it? Can I return it?
No worries — we offer a 14-day return policy. Just contact us, and we’ll make the process quick and easy.
