My Health Data at Home: Iphone & Iwatch

I'd like to see an article that explains all the ways that the iphone and watch can be used to measure key health metrics.  Many people seem fascinated by having a target number of steps.  I'm looking for more than that.  

 What can I see and do?

Heart Rate. Instant Heart, iPhone - app on phone gives me, after some seconds with my finger over the camera (middle lens). My heart rate: 54-57 bpm 10/24/25

Heart Rate. iWatch - Clicking on iWatch app for BPM: Heart Rate. 53 bpm 10/24/25

ECG app. iWatch with iPhone.  Put finger on crown for 30 seconds. watch gives BPM (51). On the phone, there's info from it on Sinus Rhythm, Atrial fibrillation

Blood oxyogen. App on phone called Blood Oxyogen.  99%.

Weight. Renpho

Best way to measure blood pressure?  Need a cuff that talks to the phone.

Data Flow

Anyway to get my weight and other data sent from Renpho into Apple Data flow?

Any comprehensive reports?

Workouts. I'll try to keep the iwatch on and activate it when I exercise. I tried today when I spent some time on a tennis court but I don't seem to have activated it until after I had finished. Typical. ;-<

So I asked AI. Here's the key points:

The Apple Watch tracks a range of metrics, such as heart rate, activity, sleep, and blood oxygen, which are all sent to the Apple Health app for a comprehensive overview. 

Heart health

Your Apple Watch monitors your heart rate throughout the day and can alert you to irregularities.

• Notifications: Receive alerts for unusually high or low heart rates. On supported models, you can also be alerted to irregular heart rhythms that could be a sign of atrial fibrillation (AFib).
• ECG app: On newer models, take a single-lead electrocardiogram (ECG) at any time to check for signs of AFib. You can share the reading as a PDF with your doctor.
• Hypertension alerts: On Apple Watch Series 9 or newer, you can receive alerts for potential hypertension based on heart data. 
  
  
  Activity and fitness
  The Apple Watch and iPhone automatically track your movement.
  • Activity rings: The Activity app on both devices helps you track your progress toward your Move, Exercise, and Stand goals.
  • Workouts: The Workout app on your watch lets you track specific activities like running, cycling, or swimming, collecting detailed data on your performance.
  • Steps and distance: Your iPhone and Apple Watch automatically track your steps and distance. All the data is aggregated in the Health app.
  Sleep tracking

  By wearing your Apple Watch to bed, you can monitor your sleep patterns.

  • Track sleep: Set a sleep schedule in the Health app to track your sleep duration and time spent in different sleep stages.
  • Vitals app: This app provides a consolidated look at overnight metrics, including heart rate, respiratory rate, wrist temperature, blood oxygen, and sleep duration.
  • Sleep apnea notifications: On supported models, your watch can monitor for signs of sleep apnea, a condition that can interrupt breathing during sleep. 

  Other important metrics

  • Blood oxygen: On supported Apple Watch models, you can measure your blood oxygen saturation using the built-in sensor.
