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. INCLUDED IN THIS RELEASE • Adaptive age from a blood panel (PhenoAge, Levine 2018) • On-device deterministic scoring • 48-hour fast protocol with safety screen • Health Connect & Withings connectors (opt-in) • Nutrition, movement, sleep and hydration tiles • Consented research cohort (opt-in) Delta is a wellness product, not a medical device. Nothing in the app replaces your clinician. Terms: https://deltahealth.fit/terms Privacy: https://deltahealth.fit/privacy Support: info@deltahealth.fit © 2026 Vulti Holdings Limited
