PeakSpan is your personal healthspan dashboard from OxyPeak Longevity Institute. It takes the complex health data you already generate - blood lab work, body composition scans, cognitive assessments, sleep and fitness telemetry - and translates it into one clear, physician-designed number: your PeakLife Score. PeakSpan is free to download and use. Designed by OxyPeak Longevity Institute, the PeakLife Score measures long-term vitality across seven pillars of health: Brain Sharpness & Focus — memory, attention, processing speed and executive function from CNS Vital Signs testing Fitness & Oxygen Capacity — VO2 Max, resting heart rate and heart-rate recovery Metabolic, Heart & Kidneys — blood pressure, ApoB, HbA1c, kidney function and hs-CRP inflammation Body Composition & Strength — skeletal muscle mass, visceral fat, grip strength and sit-to-stand power Daily Lifestyle & Habits — nicotine-free living, weekly exercise, active movement and alcohol moderation Sleep & Nightly Recovery — total sleep, deep sleep and REM, synced from Apple Health Hormone Balance & Vitality — thyroid and key vitality hormones, matched to your age and sex SMART SAFETY CEILINGS If a critical risk is detected — such as active nicotine use, high blood pressure, elevated HbA1c or reduced kidney function - your score is capped until that issue is addressed with your clinical team. Resolving a major risk flag is the single biggest step you can take for your longevity, and PeakSpan makes that priority impossible to miss. WHAT YOU CAN DO SCORE — See your PeakLife Score ring and Morning Readiness gauge at a glance. Tap any pillar for an instant breakdown of what's driving your number.
