Optional: Reaction Test

A slower reaction time can predict health risks. Tap below if you want to measure yours (~1 minute).

Optional: Face Age Analysis

Your face offers a unique window into your overall well-being. Our AI-powered Face Age Calculator analyzes features like skin texture, wrinkles, and evenness to estimate your biological age from a photo. This provides a valuable data point that, when combined with your other results, contributes to a more holistic understanding of your health and aging process.

Your Body Age Results

Calculate Optimal Protein Intake

This Biological Age Calculator blends data from major epidemiological studies with the latest "Hallmarks of Aging" research to estimate your potential lifespan and biological age. Think of these results more as directional guidance—highlighting where your health profile looks favorable and areas to watch or improve.
