Understand Your Body.
Over Time.
PRANA Ring tracks sleep, recovery, stress, and physiological age — continuously. Giving you the clarity to live better, longer.
Your body is constantly communicating — through heart rate, temperature, sleep patterns, and subtle shifts in your nervous system.
PRANA doesn't just track these signals. It learns your baselines, understands your trends, and helps you see the bigger picture of your health — not just today, but over months and years.
A system, not a gadget
PRANA is designed around three core principles that work together to transform how you understand your body.
Measure
Continuous, research-grade biometric tracking. Heart rate, HRV, temperature, blood oxygen, sleep stages — all captured silently, 24/7.
Understand
Your data becomes insight. PRANA learns your unique patterns, establishes your baselines, and surfaces what matters most.
Improve
Actionable guidance, not overwhelming alerts. Know when to push, when to rest, and how your choices affect your long-term health.
Sleep is the foundation of health
PRANA tracks every stage of your sleep — Deep, REM, Light, and Awake — along with overnight heart rate, HRV, breathing rate, and blood oxygen. Understanding these patterns reveals how restorative your sleep truly is.
Your heart tells the story of your health
Continuous heart rate monitoring reveals your cardiovascular fitness and recovery state. HRV — the variation between heartbeats — is one of the most powerful indicators of overall health, stress resilience, and readiness.
Detect overload before you feel it
Your body responds to stress in ways you can't always feel. PRANA uses HRV patterns and physiological signals to show when your nervous system is under strain — often before symptoms appear.
See your stress patterns throughout the day, identify triggers, and get personalized guidance for recovery — whether that's a breathing exercise, a walk, or simply rest.
Progress without obsession
Track steps, workouts, and active calories — but more importantly, understand how your activity connects to your recovery and long-term fitness. PRANA measures what matters: your VO₂ max and fitness age.
Your Age,
As Your Body Feels
Physiological age is PRANA's signature insight — a single number that represents how old your body actually is, based on long-term biomarker trends. It's not calculated daily, because real health changes take time.
Built from cardiovascular fitness, HRV trends, sleep quality, recovery patterns, and metabolic indicators. Updated monthly as PRANA learns more about you.
