Everything Kokaru understands about you

A real-time energy battery: it recharges with rest and drains with demand.

• Overnight recovery as your starting point
• Drain from physical load and stress
• Recharge from rest and calm

It reads your physiological activation against your own rest and shows you which state you're in right now.

• Activation measured against your own rest
• Trend across the day
• Basis validated with published evidence

It integrates your sleep debt, hours awake, and effort to estimate your fatigue.

• Accumulated sleep debt
• Hours awake and effort
• Anticipates your need for rest

It estimates your drowsiness by combining heart rate and temperature signals.

• Sleep pressure and alertness
• Windows of low attention
• Aligns with your circadian rhythm

It flags when physiological demand stays high for too many days in a row.

• A multi-day window
• Stress + load + recovery
• Recommendations to unload

It estimates the strain that heat places on your body during effort or in warm environments.

• Relevant in sport and heat
• Hydration and rest cues
• An orienting indicator, not a medical one

Heart Rate Recovery measures how much your pulse drops right after effort, a marker of your cardiovascular condition.

• Marker of cardiovascular condition
• Reflects your recovery
• Improves with training

An estimate of VO₂ Max, how much oxygen your body can use, to track your aerobic fitness over time.

• A reference for aerobic fitness
• An estimate without a lab test
• Useful for tracking your progress

Autonomic Tone reflects the balance between activation and recovery in your nervous system.

• Based on heart rate variability
• Recovery and resilience
• Compared against your own baseline

It evaluates how well your heart raises its rate according to the demand of exercise.

• Pulse response to exercise
• Complements VO₂ Max and HRR
• An orienting indicator

It observes how your autonomic nervous system responds around your meals. It does not measure glucose.

• Your nervous system's response after eating
• Draws on your meal markers
• Does not measure glucose or blood sugar

Exclusive to the KB8: a single-lead ECG to see your heart rhythm, plus screening for irregular rhythm.

• Single-lead ECG (KB8 only)

Duration, stages (deep, light, REM, and awake) and a Sleep Score, with the recovery they gave you.

• Sleep architecture by stage
• Sleep Score per night
• Recognizes naps (biphasic)

It tracks the fragmentation of your sleep night by night and screens for irregular breathing patterns.

• Sleep fragmentation
• Screening for irregular breathing pattern
• An orienting signal, not a diagnosis

It tracks the variation in your body temperature while you sleep, against your own baseline.

• Personal thermal baseline
• Sensitive to recovery and cycle
• Context for your sleep

How much the night recovered you: nocturnal HRV, sleep, and resting heart rate combined.

• Nocturnal HRV
• Resting heart rate
• Feeds the day's energy

Tracks the activity of your parasympathetic branch, the 'brake' that restores you, through the night.

• The restorative side of your nervous system
• Complements Nocturnal Recovery
• Compared against your own baseline

Estimates where your biological clock stands and whether you're in sync with it.

• Best time to sleep
• Detects schedule misalignment
• Improves energy and mood

Tracks your respiratory rate and its stability through the night.

• Nighttime respiratory rate
• Regularity of the pattern
• A signal of sleep quality

Measures the regularity of your sleep and activity schedules, key to a healthy biological clock.

• Bedtimes and wake times
• Day-to-day stability
• The basis of a healthy circadian rhythm

Log your mood and track your Mental State Index (MSI), a summary of your mental balance.

• Mood logging
• Mental State Index (MSI)
• Correlation with sleep and stress

Guided breathing and meditation sessions to lower stress and switch on your recovery.

• Short sessions
• Follows the physiological effect

Brief wellbeing check-ins that complement your physiological signals with how you feel.
