Bought this as a surprise for my wife and she loves the gold version. I tried it on myself and the heart rate tracking is surprisingly accurate for a run. Great value.

The gold color is so soft and matches every outfit. It is more than just a health tool, it is a legit fashion accessory. Totally worth it.

At my age, I just want to sleep peacefully. This ring is so lightweight I forget I am wearing it. Checking my sleep data in the morning has become my new routine.

Not having a mandatory subscription is a huge plus. The app opens fast and syncs right away. If you hate monthly fees, just get this one.

Why Quriov

A small thing you'll keep choosing.

Useful from day one

It earns its place immediately — clear insight into your rest and movement, no setup marathon, no learning curve.

Yours, over time

The longer you wear it, the more your patterns come into focus — quietly building a picture that's genuinely your own.

The first step

The ring is where Quriov begins. What it learns becomes the foundation for everything we're building next.

  • CE
  • IP68
  • RoHS
Good to know

Questions, answered.

Is the Quriov Smart Ring waterproof?

Yes - it is rated IP68, so it is fine for handwashing, showering, and swimming.

How long does the battery last?

Up to about 5 days on a charge, depending on use. A full charge takes roughly 30 minutes on the magnetic charging cable.

How do I choose my ring size?

The ring comes in US sizes 7-13. We recommend measuring your finger before ordering, so you get the right fit the first time.

Which app do I use with the ring?

Set up and sync your ring with a free companion app, available on iOS and Android.

Is the Quriov Smart Ring a medical device?

No. It is designed for general wellness and fitness. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or condition.

The journey

The ring is step one.

It's a genuinely good wearable today — and the first way Quriov gets a sense of your days. We're building toward an assistant that understands them, and, in time, the glasses it was always meant to live in.
