morning briefing

Start the morning with state

Before the day begins, organize recovery, stress, and post-sleep feedback into a few clear priorities.

training window

Train without forcing it

Combine HRV, heart rate, and recent load to help users decide whether to push, maintain, or recover today.

calm check

Step in gently when needed

When tension persists, HealthBuddy can place breathing, reflection, and short reminders at better moments.

From body signals to daily rhythm, keep only the judgments that matter.

HealthLight does not chase chart overload. It combines long-term signals, daily changes, and active records into state references that can be reviewed, compared, and acted on.

01

Gather

Bring authorized Apple Health data and active records together so stress, HRV, heart rate, and training no longer sit in separate places.

02

Summarize

Place fluctuations back on a timeline and highlight recovery windows, training load, and sustained tension.

03

Plan

Bring results into today: training intensity, recovery priority, breathing sessions, and work rhythm in shorter paths.

Health information should be clear, gentle, and traceable.

HealthLight prioritizes permission, source explanation, and restrained wording. Every state cue aims to show which signals it comes from, how it should be read, and what can be adjusted next.

Visible permissionUsers can see which data is used for state reference.
Clear sourcesKey cues map back to stress, HRV, heart rate, or training records.
Consistent across languagesChinese and English keep the same meaning to reduce misreading of health information.

Put HealthLight into a real day.

The user guide follows a real usage path: permissions, today's state, breathing sessions, feedback, and the signal sources behind each cue.
