    What Sam tracks for cardiovascular health

    The same data your doctor wants - in a format you can actually understand between visits.

    Resting Heart Rate Trends

    Track your resting HR daily against your personal 30-day baseline. Spot multi-day elevations or drops worth mentioning to your cardiologist - not just today's number, but the full month's story.

    HRV Monitoring

    Heart rate variability reflects your autonomic nervous system's state. Sam tracks your HRV pattern and flags meaningful deviations from your norm - useful context for cardiovascular wellness tracking and for informed conversations with your cardiologist.

    Monthly PDF Report

    Doctor-friendly summary of your cardiovascular metrics every month. Formatted to be useful at appointments - bring it to your cardiologist, keep it in your records, track your progress year-on-year.

    Stress Score & Sleep Quality

    Stress and sleep quality are closely linked to cardiovascular wellness. Sam tracks both against your personal baseline and highlights sustained trend changes worth discussing with your doctor.

    Go Further

    Build healthy habits alongside your daily monitoring.

    Three self-improvement programs complement your daily tracking: structured movement, better sleep quality, and steadier stress levels, all self-directed.

    How Sam fits into managing your condition

    Three steps. One habit. Better conversations with your doctor.

    1

    Connect once

    Link your Apple Watch or Oura Ring through Apple Health. Sam reads your data automatically every day - no manual entry, ever.

    2

    Weekly pulse check

    Each week, Sam surfaces a plain-language summary: "Your resting HR was stable. HRV dipped mid-week but recovered. Nothing urgent." You stay informed without obsessing.

    3

    Monthly report ready

    At month-end, download your PDF health report. It summarises your cardiovascular metrics in a format your doctor will appreciate - bring it to your next appointment.

    Sam isn't your doctor. But it helps you have better conversations with them.

    Sam does not diagnose conditions or replace your physician's care. It gives you better information so your doctor can give you better care. Always follow the advice of your qualified healthcare provider.
