Why it works

Built on four ideas.

The same four things the app shows you the first time you connect a ring — here is what they actually mean.

  • 01

    Biometric Tracking

    Optical and thermal sensors sample heart rate, HRV, SpO₂ and skin temperature through the day, with a fresh reading every hour of the night — no screen to check, nothing to remember.

  • 02

    Body-activated Sync

    Paired devices respond to your biometrics in real time. Your body sets the pace; the ring keeps everything in step.

  • 03

    Private Bio Model

    Every insight is measured against your own long-term baseline, not a population average. The model is built from you, for you.

  • 04

    Patented Algorithm

    Patented physiological models turn raw signals into Body Power, Recovery and Relaxation — numbers you can plan a day around.

Sleep

Sleep, staged.

Five stages, one night at a time. Body Power starts from last night's score — the better you sleep, the more you have to spend.

AI Assistant

Ask your ring anything.

Not a chatbot bolted on — an assistant that has read every night and every heartbeat, and answers with your own numbers.

  • Grounded in your baseline

    Every answer is checked against your own 30-day history before it reaches you.

  • The why, not just the number

    Sleep insight, Recovery and Cycle notes explain what moved and what to do next.

  • Private by design

    Your bio model is yours. Synced history stays on your phone, even if you unbind the ring.

Reading your last 30 days

Online

  1. Why do I feel drained today?

  2. Your HRV came in 18% under your 30-day baseline, and you fell asleep at 01:12 — 74 minutes later than usual. Body Power started the day at 61%.

  3. Keep today light: a walk instead of intervals, and lights-out by 23:30. I'll check your recovery tomorrow morning.

Design

Built to disappear.

A seamless titanium shell, a matte inner band and three sensor windows that sit flush against the skin. Light enough to forget, tough enough to keep on.

FAQ

Questions, answered.

Everything else is one message away.

Is metaXring a medical device?

No. metaXring is a wellness product. Its readings are for everyday trend watching and cannot be used for diagnosis or medication decisions.

How does the ring sync with my phone?

Over Bluetooth LE to the metaXring app on iOS and Android. Data syncs automatically whenever your phone is nearby.

Which phones work with it?

iOS and Android today, with a HarmonyOS app in development. The app ships in 16 languages.

How does sleep tracking work?

The ring stages your night as Awake, Drowsy, Light, Restful and Deep from heart rate, HRV, temperature and movement, then compares it with your own baseline. Wear it overnight and Body Power is ready when you wake.

Is my data private?

Insights are computed against your own baseline — a private bio model. Synced health history stays on your phone even if you unbind the ring.

Can I wear it in the shower or pool?

Yes — see the water-resistance rating in the specs above. Rinse it with fresh water after swimming in the sea.
