Questions? We've got answers
What is biological age?
Chronological age counts your birthdays. Biological age estimates how old your body functions based on lifestyle, stress, sleep and visible aging markers — it can be years above or below your passport age.
How is my biological age estimated?
Our AI combines your lifestyle assessment with optional facial aging markers from a selfie and compares the pattern against thousands of profiles to place your body on the aging curve.
Is this a medical test?
No. It's an educational estimate based on your answers and photo — not a lab test or a diagnosis. It's designed to show you what's driving your aging and what you can change.
Can I actually lower my biological age?
Research shows sleep, exercise, nutrition and stress management can measurably improve aging markers. Your report includes a 30-day plan focused on your weakest areas.
Do I have to upload a photo?
No — the photo is optional. Adding one lets the AI read visible aging markers and makes your estimate sharper, but you'll get a full report either way.
