Measure in the evening, when fingers are at their largest. Avoid measuring when your hands are cold.

  1. Cut a strip of paper about 5mm (0.5cm) wide and 10cm long.
  2. Wrap it snugly around the base of the finger you'll wear the ring on.
  3. Mark where the paper overlaps, then measure that length in mm.
  4. Match it to the table below. Between sizes? Go up one.

Smart Ring · Health Tracker

Know your body 24/7
with sharper sensors.

Most people only notice their health when something feels off. QuantumRing2 keeps you a step ahead with a next-gen sensor array for sharper readings, wrapped in a slimmer, sleeker band. It tracks around the clock so you can spot patterns, dodge burnout and make smarter calls every single day. The next big ring thing, basically.

7-day battery: charge it less than your phone
3–4.5g: so light you'll forget it's on
5 ATM: swim, shower, sweat, repeat
Sizes 7–14: hands down our widest range
What it tracks (spoiler: a lot)

Fat Burning & Exercise

Find out when you're really in the fat-burning zone, not just going through the motions. Calories burned and heart zone performance included.

Heart Rate & HRV

Real-time heart rate and HRV from sharper sensors, so you can take your recovery to heart.

Stress Levels

Catch burnout before it catches you. Tracks your stress all day, so you know when to take it down a notch.

Sleep Quality

Wake up knowing exactly why you're tired, and what to do about it. A full sleep stage breakdown every night, so you can stop sleeping on your sleep.

Blood Oxygen (SpO₂)

Round-the-clock blood oxygen monitoring. A breath of fresh data on how your body is performing.

Body Temperature

Spot early signs of illness or overtraining before you feel them. It's a hot topic, so we track it continuously.

Menstrual Cycle Tracking

Predicts your cycle phase and fertility window, so you're always one step ahead of the cycle.

Ordered 2 rings for my partner and I. They are brilliant rings to track everything we need. 1 ring was not working correctly. Joel was very prompt at helping to fix the ring. When he realised it was faulty, the return was prompt and a new ring was sent out. Joel was awesome and so are the rings

The Quantum Ring 2 is a major leap forward from the first version. It is refined, comfortable, stylish and functional. This ring packs a lot of the features of far more expensive rings into a much more attractive sell price. No hesitation in recommending this ring.
