Syn Health

Syn is your personal health companion designed to help you understand your body, build better habits, and stay private while you do it. YOUR HEALTH, PRIVATELY POWERED Syn brings together Apple Health data, guided plans, streak challenges, and on-device AI in one calm place. Insights are written for you, not for advertisers. A DAILY BRIEF, MADE FOR YOU Each day, Syn turns your sleep, steps, heart rate, and energy into a short personal briefing. On-device AI keeps the thinking on your iPhone whenever Apple Intelligence is available so your health story doesn’t need to leave your device to be useful. TRACK WHAT YOUR BODY DOES Connect Apple Health to see the signals that matter: sleep, steps, heart rate, and active energy. Your metrics stay grounded in the data you already trust. BUILD HABITS THAT STICK Follow guided plans, keep streaks going, and discover challenges made for real routines, not crash programs. Check in with friends, celebrate progress, and stay consistent over time. PRIVATE BY DESIGN Share health updates only with people you choose. Emergency briefs can be protected with end-to-end encryption, and access can be revoked. Sharing events are recorded on a public audit ledger so transparency isn’t an afterthought. DISCOVER WHAT HELPS Browse articles, videos, and recommendations curated for wellness, mobility, recovery, sleep, and everyday health so you always have something useful to try next. ASK SYN Chat with your on-device assistant about how you’re doing or, when someone has shared their health with you, ask how they’re doing today. Answers stay supportive and non-diagnostic. WHAT YOU GET • Personalized daily briefs powered by on-device AI • Apple Health integration for sleep, steps, heart rate, and energy • Plans, streaks, and friend progress • Articles, videos, and recommendations • Encrypted emergency sharing you control • Notifications that respect quiet hours and your preferences Syn is built for everyday wellness. It is not a medical device and does not provide diagnosis or treatment. Always talk to a qualified clinician for medical advice.
