Is Yesil Health a replacement for my doctor?

No. Yesil gives you educational, evidence-based health information and helps you track and understand your habits. It does not diagnose, prescribe, or replace professional medical care. Always consult a qualified clinician for medical decisions.

Where do the answers come from?

Important recommendations cite their sources — peer-reviewed papers from the entire indexed medical literature (250M+ articles), FDA drug data, and every registered clinical trial. When the evidence is weak or mixed, the app tells you so instead of guessing.

What about my privacy?

Your health data is encrypted in transit and at rest. We don't sell it, and we don't train third-party foundation models on it without your permission. Sign in with Apple is supported.

Which devices and languages are supported?

Yesil Health runs on iOS and Android, syncs with Apple Health, Google Health Connect and Bluetooth devices, and speaks 9 languages: English, Türkçe, Español, Deutsch, Français, 日本語, 한국어, العربية and 中文.

Can I use Yesil on the web?

Yesil is a mobile app for everyone — we don't have a consumer web app right now, so your phone is the AI. The web product at pro.yesilhealth.com is designed for clinicians: a professional view of the same engine for reviewing patient-shared data, querying the evidence engine, and generating visit-ready summaries.
