LetoCare vs Your Echo

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. Free to use.

YOUR HEALTH HAS A STORY. START A CONVERSATION. Some days you want more energy. Some days you want to understand a report, make sense of your sleep, or find a workout routine you can keep. Start with Echo. Bring the question that matters to you, and build from there. Your Echo currently requires an invitation. Have a code? Download the app and redeem it after sign-in. Need access? Request it at support@yourecho.xyz. MORE THAN A NUMBER Connect Apple Health or a supported wearable account to explore your sleep, activity, heart measurements and recovery alongside the things you tell Echo. See your patterns, ask follow-up questions and understand what is available in your record. Measurements depend on your device, permissions and sync history. A TEAM THAT FITS YOUR FOCUS Talk with a specialist about sleep, nutrition or training, or describe the specialist you need. Keep separate conversations for separate topics and return to them from the conversation sidebar. Available specialists and capabilities depend on your access. KEEP THE CONTEXT Save useful conversations as topic notes. Pin the topics that matter, update them as your thinking changes, and use a note to start a new conversation with Echo or a specialist. BRING THE DETAILS Attach photos and PDFs together. Talk through a written health report, prepare questions for your clinician, or log a meal with estimated nutrition. Keep uploaded sources, extracted information and summaries in your record. Food estimates and AI explanations can be wrong; review important information against the original. SMALL STEPS, IN REAL LIFE Work through a goal, shape a practical plan, or set a routine in conversation. Talk by voice where calling is available. With notification permission, Echo can reach out about your data and scheduled updates; manage preferences in Settings.
