Matte Smart Ring

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 work well — just avoid the thumb or pinky for less reliable tracking.

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.

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.)

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.

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.

On a full charge, the ring typically lasts 3–7 days, depending on usage.

It takes about 1 to 1.5 hours to fully recharge using the included magnetic charger.

No worries — we offer a 14-day return policy. Just contact us, and we’ll make the process quick and easy.
