What the app does

Reads heart rate, resting heart rate, and date of birth from Apple Health with your permission.
Calculates time spent in moderate and vigorous cardio zones.
Shows daily, weekly, and monthly progress toward a weekly exercise target.
Can show demo data without reading HealthKit, which helps with onboarding and App Review.

If reports look empty, confirm the app has Health access in the Health app and that your watch or other source has written heart-rate samples.
If your zones feel off, open Profile and review age, resting heart rate, and target range.
If you only want to preview the UI, use Show demo data on the welcome screen.

LDL Reduction is designed to keep health data on-device. It does not include analytics, ads, tracking SDKs, user accounts, or backend servers.
