Open Vital turns your Garmin watch into a complete recovery and performance platform. Track strain, monitor recovery, analyze sleep, and get AI-powered coaching — all from one app.

RECOVERY SCORE
Know exactly how ready your body is each morning. Vital OS computes a 0-100 recovery score from your HRV, resting heart rate, sleep quality, stress levels, and body battery — then tells you whether to push hard, train smart, or prioritize rest.

WHOOP-STYLE STRAIN
Track cardiovascular load on a 0-21 logarithmic scale modeled after WHOOP's strain algorithm. Vital OS uses your Garmin heart rate data to calculate accumulated EPOC (Excess Post-Exercise Oxygen Consumption) throughout the day, with a full breakdown of time spent in each heart rate zone.

SLEEP ANALYSIS
Deep dive into your sleep performance with stage-by-stage breakdowns (deep, light, REM, awake), sleep efficiency, consistency tracking, and sleep debt monitoring. The Smart Sleep Planner calculates your ideal bedtime based on your recovery status and sleep goals.

HEALTH MONITOR
Track every vital in one place: HRV, resting heart rate, SpO2, respiratory rate, VO2 max, body battery, stress levels, and more. Spot trends and anomalies across all your biomarkers.

AI COACH
Get personalized daily guidance powered by AI. The Vital Coach analyzes your recovery, strain, and sleep data to recommend target strain ranges, flag when you need rest, and help you make smarter training decisions.

CUSTOMIZABLE DASHBOARD
Build your dashboard your way. Choose which metrics to display, reorder cards, and focus on the data that matters most to you. Over 20 metric cards available.

COMMUNITY & TEAMS
Create or join teams to compare strain, recovery, and sleep with friends. Daily rankings, team competitions, and social accountability keep you motivated.

JOURNAL & BEHAVIOR TRACKING
Log daily habits — caffeine, alcohol, meal timing, gratitude, light exposure — and discover which behaviors actually impact your recovery. Vital OS correlates your habits with your biometrics so you can optimize what works.

GAMIFICATION
Earn levels from Carbon to Diamond across 30 tiers. Track streaks for sleep, recovery, and daily logging. Hit milestones and watch your consistency compound.

STRAVA INTEGRATION
Connect your Strava account to pull in activity data alongside your recovery metrics.
