Find your ring size

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.
Size (US)Circumference
857.5 mm
960.0 mm
1062.8 mm
1165.4 mm
1267.8 mm

Every size is 7mm tall and 2.7mm thick. Only the inside diameter changes with your size.

Smart Ring · Health Tracker

Know your body 24/7
without the watch.

Most people only notice their health when something feels off. QuantumRing keeps you one step ahead, tracking around the clock so you can spot patterns, dodge burnout and make smarter calls every single day. Think of it as your body's new ring leader.

7-day battery: charge it less than your phone
3g: so light you'll forget it's on
5 ATM: swim, shower, sweat, repeat
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 heart rate variability, 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.
