Charge without taking it off

Slide the battery pack onto the pod and keep wearing it. Your data never has a gap.

Strain and recovery

The band learns how hard you can push and tells you when to back off.

Wrist or bicep

The bicep sleeve keeps the sensor still during lifting and rowing, when wrists get noisy.

What it measures

9 metrics. Tap one to see how we measure it.

Heart rateHow fast your heart is beating, measured continuously or on demand. Heart rate variabilityThe small beat-to-beat changes in timing that reflect how rested your nervous system is. Blood oxygenHow much of your blood's haemoglobin is carrying oxygen. Irregular rhythm alertsPassive checks for signs of atrial fibrillation while you go about your day. Sleep stagesHow long you slept and how the night split into light, deep and REM sleep. Skin temperatureOvernight changes in skin temperature, used to spot illness and cycle phases. Respiratory rateHow many breaths you take each minute while asleep. VO2 max estimateAn estimate of your aerobic capacity, the best single predictor of long-term health that a wearable offers. Stress and recoveryA composite score built from heart rate, variability, sleep and sometimes skin conductance.
