KLU Longevity

Your blood holds the clues to your health — KLU helps you understand them.

Snap a photo or upload a PDF of your blood test results, and KLU analyzes up to 87 biomarkers across 12 body systems — from heart health and metabolism to hormones and inflammation. Connect your wearables for a complete picture of your wellness.

What you get:

• A personalized Longevity Score that tracks how well your body is aging
• Your estimated Biological Age — a wellness indicator based on your biomarker profile
• Color-coded biomarker breakdowns so you see what's in range and what may need attention
• Trend tracking across multiple blood tests to monitor changes over time
• Fitness and recovery insights from your wearable devices
• An AI Longevity Coach you can ask questions about your results

Wearable & Health Integrations:

• Apple Health — reads steps, heart rate, resting heart rate, sleep duration, active calories, and blood oxygen (SpO2) to complement your blood test insights. KLU does not write data to Apple Health.
• Oura Ring — connect your account to sync sleep, readiness, activity, and heart rate data.
• WHOOP — connect your account to sync recovery, strain, sleep, and workout data.

All wearable connections are optional and require your explicit authorization.

1. Upload your blood test (photo or PDF)
2. KLU extracts and organizes your biomarkers automatically
3. Optionally connect Apple Health, Oura, or WHOOP for fitness data
4. Review your score, trends, and educational insights
