Apple Watch 4 Heart Rate Complication - Infograph Modular Face

I love the idea of the center position heart rate complication in the new AW4 Infograph Modular face, however after wearing for a few weeks, it seems to be highly inconsistent and somewhat inaccurate. For example, it never displays "now" as a time frame and mostly fluctuates between the recent past and distant past with significant time lapses, sometimes up to 40 minutes, in between. Is this how it's supposed to work? It seems like it would measure more regularly and I would catch it with a current reading every now and again. Any info about other's experiences would be greatly appreciated. Thank you.

Hi, jmkjmk!

Thanks for stopping by the Apple Support Communities. If I understand your post, you have some questions regarding when your Apple Watch monitors your Heart Rate, and thus how the Heart Rate complication displays the information. I'm happy to help!

The information below, from Your heart rate. What it means, and where on Apple Watch you’ll find it. - Apple Support , details when Apple Watch monitors your heart rate:

When Apple Watch measures your heart rate

User uploaded file

When you use the Workout app, Apple Watch measures your heart rate continuously during the workout and for 3 minutes after the workout ends to determine a workout recovery rate. If you don't see your heart rate, check your settings.

This information, as well as other data it collects, helps Apple Watch estimate how many calories you’ve burned. In addition, Apple Watch measures your heart rate throughout the day when you’re still, and periodically when you’re walking (Apple Watch Series 1 or later). Since Apple Watch takes these background readings based on your activity, the time between these measurements will vary. Apple Watch also calculates a daily resting rate and walking average by correlating background heart rate readings with accelerometer data when sufficient background readings are available. You can control which third-party apps have access to your health data from the Health app in Sources.

Some anomalies may appear in the displayed data, resulting in occasional heart rate measurements that are abnormally high or low.



To ensure you're getting an accurate heart rate reading, make sure you have a good fit: Wearing your Apple Watch - Apple Support and you can get information on what affects your reading here: Get the most accurate measurements using your Apple Watch - Apple Support .
