Decades App — Biological Age & Longevity Platform

What is Decades

A whole preventive-health system, in one app.

Decades brings biological-age science, validated clinical risk calculators, a structured lab decoder, an AI Doctor Coach, longevity planning tools, and family-scale tracking together in a single mobile app. It is the life-course companion to PAUSE: where PAUSE screens digital behaviour in young adults, Decades measures and improves preventive health across the decades that follow.

📊

Your score & daily ritual

One number for where you stand.

The home dashboard distils everything into a single Decades score, a biological-age delta, and one realistic action for today.

Decades Score

A composite preventive-health score with your biological-age delta versus chronological age.

Daily Drop & Today's Action

One fresh, realistic preventive action each day — the smallest high-value thing you can do now.

40-Year Health Roadmap

A decade-by-decade visualisation of your preventive-health trajectory and what to prioritise next.

Decades Day

A daily ritual / habit anchor that keeps the routine consistent over months.

Age-band Screening Reminders

The right screening tests for your age, surfaced when they're due.

Profile & Onboarding

Guided setup — basics, goals, history, labs, lifestyle, and consent — feeding every engine.

🧪

Lab decoding — the wedge

Upload a report. Get the real read.

The structured biomarker decoder is the heart of Decades — it turns a photo or PDF of a lab report into validated risk scores with an Indian-norm reference overlay.

Decode-v2 Structured Decoder

Reads a lab report and runs 10 peer-reviewed risk calculators on the biomarkers — deterministic math, with an AI narrative on top.

10 validated calculators

Image & PDF Lab Decode

Upload a photo or PDF of any lab report; Decades extracts and interprets the values.

Indian-Norm Overlay

28 biomarkers classified against Indian-specific reference ranges (LAI 2016/2020, ICMR-INDIAB, IDF South Asia, AASLD 2023, ICMR Vit D, WHO Asia-Pacific BMI), sex-adjusted.
