Delta: Track your health

Delta reads a standard blood panel and turns it into your adaptive age — on your device.

HOW IT WORKS
• Photograph any standard blood panel (PDF or image). Delta reads it and keeps nothing.
• Delta computes your adaptive age using the deterministic PhenoAge formula published by Levine et al. (2018). Same inputs, same answer.
• Bracket a defined 48-hour fast with three draws and read how your number responds.

WELLNESS, NOT MEDICAL ADVICE
Delta is a wellness product. It does not diagnose, treat, cure, or prevent any disease. It never provides dosage guidance. Adaptive age is a functional score, not a medical result. Care decisions stay between you and your clinician.

TWO SIGNALS, NEVER CONFUSED
• LEVEL — the multi-year gap between your adaptive age and your calendar age. Annual draws move it slowly.
• DYNAMICS — how your number responds inside a single 14-day cycle. This is the signal you can act on.

THE SAFETY SCREEN COMES FIRST
The 48-hour fast is a real physiological stress test. Delta refuses to schedule one for anyone under 21, or for anyone with type 1 diabetes, pregnancy or breastfeeding, a history of disordered eating, advanced kidney/liver/cardiac disease, or concurrent SGLT2 inhibitors, insulin or sulfonylureas. A block is a block, not a warning.

BEYOND THE BLOOD
Optional connectors from Health Connect and Withings render movement, sleep, HRV, resting heart rate and body-composition trends alongside your adaptive age. Each connector is optional and revocable in system settings. Nutrition logging (kcal, macros, fibre) rolls into a daily rhythm.

YOUR RESULTS LIVE ON YOUR PHONE
• No login, no account server.
• Blood-panel photos are sent to Delta's analyzer to be read, then discarded — never stored.
• Everything after that stays on your device.
• Nothing is sold, nothing is used for advertising, no third-party tracking.
