LetoCare

Leto is your AI longevity twin.

Scan your face and voice for 30 seconds and Leto reads 16 wellness biomarkers — heart rate, heart rate variability, breathing, stress, vitality, and more. Then your personal AI Twin turns those numbers into a clear daily plan: what to focus on today, what's trending, and a protocol built around your body, your city, and your budget.

What you get • 30-second face + voice scan — 16 biomarkers, no wearable required • A daily briefing that tells you what actually changed and why • An AI Twin you can talk to about your data, sleep, training, and recovery • A personalized protocol — supplements, movement, recovery, testing — sized to your life • Trends over time so you can see your body responding • Apple Health sync for HRV, sleep, steps, resting heart rate, and more

Built for people who take their health seriously Leto turns scattered health signals into one place, with guidance that adapts as you do — calm, concrete, and free of jargon.

Leto is a wellness and general-fitness app. It provides wellness estimates, not medical measurements, and is not a medical device, diagnosis, or substitute for professional medical advice. Always consult a qualified healthcare provider before changing supplements, medication, training, or treatment.
