About
Yesil Health is the AI health coach that doesn't wait for you to ask.
Write one sentence: "chicken salad for lunch, slept badly, remind me to drink water at 3." Your coach logs the meal, records the metrics, sets the reminder and starts a Focus for you. No menus, no forms, all from one message.
It also writes first. When your sleep slips or your steps drop, it notices and suggests what to do next.
▸ ONE MESSAGE, MANY ACTIONS
Meals, metrics, reminders and routines are handled in the same chat. Say it the way you would tell a friend.
▸ FOCUS: ONE THING AT A TIME
Pick what matters now: sleep, hydration, movement and more. Focus gives you a themed living scene with daily steps, reminders, tracked metrics and your progress.
▸ TALK, DON'T TYPE
Hold the mic and speak. Log a meal or tell it how you feel in seconds.
▸ YOUR HEALTH, ONE PLACE
Sleep, steps, weight, heart rate and more, with 7 and 30 day trends. Syncs with Apple Health.
▸ CHARTS IN THE CHAT
Ask a question and the coach builds a chart from your own data, then explains what it means in plain words.
▸ ANSWERS WITH REAL SOURCES
Answers cite named scientific sources. Tap a citation to see the source behind the claim. When the evidence is thin, the coach says so.
▸ IT REMEMBERS YOU
Conditions, preferences, what works for you. Tell it once. Your memory is visible and you can edit it any time. It can also read lab results and PDF reports.
▸ PRIVATE BY DESIGN
Your health data is encrypted in transit and at rest. We don't sell it, and we don't train models on it without your permission.
Free to start. Yesil Coach, the optional subscription, gives you more of everything.
Yesil Health supports your wellbeing and healthy habits. It is not a medical device and does not diagnose, treat or cure any condition. It is not a substitute for a doctor. For medical decisions, talk to a qualified healthcare professional.

What's New in Yesil Health OS
1.0.32
October 23, 2026
Getting started is easier: tell your coach what brought you here, or snap a photo of your lab results or your plate to begin. When you describe a symptom, your coach now gives a full answer instead of a short note, and answers keep flowing while cards load.
