Product Title: Onyx Health Ring

Headline: Advanced Bio-Tracking. Zero Distractions.

The ultimate wearable for your active lifestyle. Track your health, optimize your recovery, and move freely without the bulk of a traditional smartwatch.

Ditch the bulky screens that get in the way of your workouts, restrict your wrist mobility, and disrupt your sleep. The Onyx Health Ring is engineered for those who take their physical recovery and daily performance seriously. Weighing just 3.5 grams with a sleek, premium stainless steel shell, it tracks your body’s most critical metrics without you even noticing it's there.

Why Onyx?

Deep Recovery & Sleep Analytics: Maximize your muscle repair and daily energy levels. The Onyx Ring continuously monitors your Heart Rate Variability (HRV), Blood Oxygen (SpO2), and Body Temperature to decode your sleep cycles and help you gauge your central nervous system readiness.

Unrestricted Biomechanics: Whether you are gripping a heavy barbell, doing mobility work, or going about your day, the ultra-slim 2.7mm profile ensures full freedom of movement for your wrist joint. No screens, no notificationsβ€”just pure, silent performance tracking.

Relentless Power on the Go: The ring itself holds up to 7 days of charge. But with the included Premium Magnetic Charging Case, you get up to 60 days of total battery life. Never worry about bringing cables on your trips again.

Element-Proof (5ATM): Fully waterproof up to 50 meters. Sweat intensely, take an ice bath, shower, or swim without a second thought.

Smart Features & Tech Specs:

Comprehensive Physiological Tracking: Precision sensors continuously monitor Heart Rate, SpO2, HRV, and skin temperature to give you a complete picture of your daily recovery.

Activity Logging: Track steps, distance, and calories accurately without a bulky watch compromising your natural kinesiology.

Smart Lifestyle Integration: Includes discreet features like remote camera control, find-my-ring tracking, and physiological cycle reminders.

Universal Compatibility: Syncs flawlessly with iOS (8.0+) and Android (5.1+) devices via our free smart companion app.

Next-Gen Connectivity: Powered by Bluetooth 5.2 (Low Energy) for instant syncing and extended battery life.

Rapid Charge Technology: Goes from 0% to 100% in just 1.5 hours via the magnetic case.

I bought it as an alternative to a smartwatch since I prefer an analog watch. It's useful for keeping track of health status. Let's hope it lasts a long time. The price paid good

I'm liking the ring; I bought it to monitor sleep and it's been working well. I found it to be durable and it fit my middle finger on the left hand nicely, but I've been using it on my right ring finger.

Good quality and very accurate. I would recommend you get your finger size measured properly by a jewellery store before buying i bought my first ring of ola esporte one size too small and therefore bought another ring from ola esporte company one size bigger. On the old ring i put it on a different finger πŸ‘‰ But best results of accuracy for measurements are best found on your index finger. Good quality and very accurate.

nice to look at, easy to install, I don't know precise for measuring blood pressure, shows more

Fast delivery and good product. The ring fits well so far and works wonderfully. Only the app seems to be a bit laggy sometimes, and synchronization takes forever until the app is ready. Also, the measurement time of 60 minutes that can be shortened to only 30 minutes seems too little to me (10 minutes would be better). But you can live with that, and the ring itself is very good and measures pulse, blood oxygen, and blood pressure. I am very satisfied with the device and can recommend it πŸ˜πŸ‘

HOW TO ENSURE ACCURACY?

  1. Measure Multiple Times: We recommend taking your measurement 3 times to ensure a consistent result.
  2. Temperature Matters: Avoid measuring when your hands are cold, as fingers tend to shrink in lower temperatures.
  3. The Knuckle Rule: The ring should be tight enough not to fall off, but loose enough to slide over your knuckle with slight resistance.
