To get continuous heart rate readings on your Apple Watch, you can either initiate a workout session, which automatically triggers continuous monitoring, or utilize specific third-party applications like Cardiogram that offer a "Continuous recording" feature.
Understanding Apple Watch's Native Heart Rate Monitoring
Your Apple Watch is designed to monitor your heart rate periodically throughout the day and more frequently during physical activity.
-
Periodic Monitoring: By default, your Apple Watch measures your heart rate at intervals, typically every 5-10 minutes when you're still. It also takes background readings and records them in the Health app.
-
Continuous Monitoring During Workouts: The most straightforward way to get truly continuous heart rate data directly from your Apple Watch is to start a workout. When you log an activity, such as a run, walk, or cycling, your watch will measure and record your heart rate continuously for the duration of the workout.
- To start a workout:
- Open the Workout app on your Apple Watch.
- Select your desired workout type (e.g., Outdoor Walk, Indoor Run).
- Tap the three dots to set a goal, or just tap the workout type to start immediately.
- Your heart rate will display continuously on the screen, and the data will be logged in the Health app.

Achieving Continuous Heart Rate with Third-Party Apps
While native workouts provide continuous data, certain third-party apps can extend this functionality for more frequent, near-continuous readings outside of designated workout sessions, offering a similar level of detail.
Using the Cardiogram App for Continuous Recording
The Cardiogram app provides a unique "Continuous recording" feature that allows your Apple Watch to collect a heart rate reading every 5 seconds. This mode is designed to capture heart rate data with an intensity similar to what you'd experience during a workout session.
- To activate Continuous recording with Cardiogram:
- Launch the Cardiogram app on your Apple Watch.
- Swipe to the left of the screen. This action will typically initiate the continuous recording mode, allowing the app to gather frequent heart rate data.
Using such a feature will provide a more detailed heart rate graph but may consume more battery life on your Apple Watch compared to passive monitoring.
Other Third-Party Options
Many other health and fitness apps available on the App Store integrate with Apple Watch to provide more frequent heart rate monitoring. These apps often focus on specific health conditions or detailed activity tracking, giving users more granular control over data collection. Always check the app's features and reviews to ensure it meets your specific needs.
Optimizing Your Apple Watch for Accurate Readings
To ensure you get the most accurate and consistent heart rate data, follow these best practices:
- Proper Fit: Ensure your Apple Watch fits snugly on your wrist, but not uncomfortably tight. It should be close to your skin to allow the sensors to work effectively.
- Clean Sensors: Regularly clean the back of your Apple Watch, where the heart rate sensors are located, to remove dirt or sweat that could interfere with readings.
- Wrist Detection On: Keep "Wrist Detection" enabled in your Apple Watch settings (iPhone's Watch app > My Watch > Passcode > Wrist Detection). This is crucial for many health features to function correctly.
- Latest Software: Always keep your Apple Watch and iPhone updated to the latest software versions for optimal performance and accuracy.
- Warm-Up: In cold weather, ensure your wrist is warm, as cold skin can sometimes affect heart rate sensor performance.
Comparing Heart Rate Monitoring Methods
Here's a quick overview of different ways your Apple Watch monitors heart rate:
| Method | Frequency | Use Case | Battery Impact |
|---|---|---|---|
| Native Workout App | Every few seconds (truly continuous) | Exercise, fitness tracking | Moderate to High |
| Cardiogram (Continuous Recording) | Every 5 seconds | Detailed daily heart rate insights, health monitoring | Moderate to High |
| Native Passive Monitoring | Every 5-10 minutes (at rest) | General health overview, resting heart rate | Low to Moderate |
By understanding these options, you can choose the method that best suits your needs for monitoring continuous heart rate on your Apple Watch.
