What should I actually do?
Personal outdoor guidance
Know the best time to go outside.

Make it personal
Your environment meets your activity.
Optional Apple Health summaries and private symptom check-ins can add wellness context. Saved places and linked family profiles help you plan beyond one location or person.
Apple Health access is optional and requires explicit system permission. Family and saved-place features have account and plan limits.
Optional Apple Health
Activity data + environmental conditions → more personal context.
With permission, HiAir can use daily and hourly summaries such as steps, heart rate, and resting heart rate. It does not need Apple Health to provide core air and heat guidance.

Science & Data
