How to set up Apple Watch for heart failure: what Sam adds - and what daily weight monitoring covers
Set up Sam for heart failure on Apple Watch, understand which metrics matter, and prepare wearable data for your next cardiology appointment.

If you live with heart failure and wear an Apple Watch, Sam supplements your daily weight monitoring without replacing it. This guide shows how the two work together.
Weight monitoring and wearable data are separate tools
Your daily weight check remains the main way to notice worsening heart failure early - regardless of what else you use. The article Resting heart rate and activity in heart failure explains why no wearable can substitute for it.
Sam is a second, independent tool. It reads resting heart rate, sleep, and activity from Apple Health - signals about your daily capacity. Weight, ECG, and blood oxygen readings are for you to discuss directly with your care team.
Setup: three quick steps
- Wear your watch regularly. Resting heart rate is calculated automatically in the background.
- Enable sleep tracking so Sam can show your sleep data.
- Connect Sam to Apple Health and grant permissions for resting heart rate, sleep, and activity.
If you use a smart scale that syncs to Apple Health, your weight will remain visible in the Health app.
The report for your cardiology appointment
You create the monthly report yourself in Sam. It puts stress, sleep, activity, symptoms and sick days into one PDF; resting heart rate you view in the app as a trend. Together with your weight records, this creates a fuller picture: the weight readings from your scale, the daily-life context from Sam.
Log symptoms in Sam and take the monthly report to your cardiology appointment
You bring a month of symptoms and daily context to the appointment instead of recalling how the weeks went.
- Instead of memory: you pick shortness of breath, leg or ankle swelling, fatigue or racing heartbeat from the symptom diary catalog, with a strength level.
- Instead of Apple Health alone: Sam reads resting heart rate, sleep and activity, and the monthly report you create puts sleep, activity and your symptom days into one PDF.
- Instead of relaying updates by phone: in Friends & Family you choose which entries someone you trust can read, read-only and revocable.
Heart failure has no program in Sam, as the heart failure page explains.
Try Sam for freeSam is a wellness companion, not a medical device. It does not diagnose, treat, cure, or prevent any illness, does not replace medical advice, and does not replace your daily weight monitoring or emergency services.

Frequently Asked Questions
Can a smartwatch replace daily weight monitoring for heart failure?+
No. A smartwatch doesn't measure weight on its own, and Sam does not replace your daily weighing. Both approaches work independently of each other. Daily weighing remains the main way to notice worsening heart failure early, as outlined in clinical guidelines.
Does Sam work with devices other than Apple Watch - like Garmin or Fitbit?+
Yes, in principle. Sam reads from Apple Health and works with any wearable that syncs to Apple Health - including Oura, WHOOP, and Garmin. Whether a specific Fitbit or Android device syncs to Apple Health depends on the individual device; check the manufacturer's sync settings. An iPhone is required either way.
Can I still log my weight in Apple Health?+
Yes. Many smart scales sync automatically to Apple Health, so your weight data sits alongside your other health metrics.
How do I prepare for my cardiology appointment using wearable data?+
You create the monthly report yourself in Sam. It puts stress, sleep, activity, symptoms and sick days into one PDF. Bring it alongside your weight records - together they give your care team a more complete picture.
