FitnessAge — AI Longevity Platform

Overview

FitnessAge calculates your biological age from a 15-minute self-assessment, then issues a personalised longevity protocol — nutrition, training, sleep and supplementation — driven by an AI coach. We built the web app and accompanying mobile app.

The Problem

Longevity science is fragmented across podcasts, supplement brands and $5k clinic visits. Consumers can't tell what actually moves their biological age, and no consumer product turns the data into a plan.

The Build

A clinical-grade biological-age model trained on validated biomarker datasets, plus a coaching agent that delivers protocols across web and mobile. Every protocol is anchored to peer-reviewed research, with citations exposed in the UI.

The Outcome

Live web + mobile apps. 15-minute protocol completion rate over 80%. Members reporting 1-3 year reductions in biological age over 6-month cohorts.
