Questions.

The Vitark V6 is a screenless smart ring made from aerospace-grade titanium. It continuously tracks your heart rate, blood oxygen (SpO₂), sleep stages, and daily activity — all without a screen. Data syncs wirelessly to the Vitark companion app on iOS or Android via Bluetooth 5.0.

The Vitark V6 includes an optical heart rate sensor, an optical blood oxygen (SpO₂) sensor, a 3-axis accelerometer, and a photoelectric sensor array. All sensors run simultaneously and update continuously throughout the day and night, with heart rate updating every 5 seconds.

The Vitark V6 is made from Grade 5 titanium alloy — the same material used in aerospace and medical devices. It is hypoallergenic, scratch-resistant, and safe for all skin types including sensitive skin. The exterior features a frosted matte finish with a polished inner edge.

Yes. The Vitark V6 carries an IP68 waterproof rating, meaning it is fully protected against water immersion up to 1.5 metres for up to 30 minutes. You can wear it while washing hands, showering, or swimming without concern.

With all sensors active during normal daily use, the Vitark V6 lasts up to 7 days on a single charge. A full recharge takes under 90 minutes using the included magnetic USB cable.

No. The Vitark V6 is intentionally screen-free and has no haptic motor. It is designed to disappear into your life and deliver insights through the app — not interrupt you with notifications or vibrations on your finger.

The Vitark V6 is available in US ring sizes 6 through 10. Size 11 is currently sold out. Refer to our size guide on the product page for exact measurements in millimetres.

Wrap a thin strip of paper around the base of your finger and mark where it overlaps. Measure the length in millimetres — this is your circumference. Match it to our size chart on the product page. We recommend measuring at the end of the day when fingers are slightly larger, and choosing the larger size if you are between two measurements.

The Vitark V6 works on any finger. For the most accurate heart rate and SpO₂ readings, we recommend wearing it on your index or middle finger. Avoid wearing it on your dominant hand during workouts for the best accelerometer results.
