Advanced Health and Fitness Tracking

Run with all your heart.

Apple Watch Ultra was designed to be the ultimate running watch, with powerful features that help you train smarter and precision dual-frequency GPS. Now Apple Watch Ultra 4 takes it to the next level with game-changing health and fitness tracking to help you elevate your performance. And new extended battery life for workouts to keep you moving toward your goals. Run better, run longer.

Heartcore innovation.

Heart data is fundamental in tracking your overall health and performance. Redesigned with more capable optical and electrical sensors, the all‑new Health Sensing System works with the S11 chip to provide higher-frequency heart monitoring. The updated sensors and larger, more power-efficient green LEDs give you richer heart data for more meaningful insights.

Ready advice. The new readiness experience can help you determine your capacity to take on the day by providing you with one simple score. Your score is determined each morning by analyzing your recent activity, vitals, and sleep — and it adjusts as you go about your day. So whether you’re training for a race or juggling a busy schedule, you can spend your energy on what matters most.

HRV? Check. Heart rate variability, or HRV, is an indicator of how your body responds to stress and recovery. Overtraining or poor sleep can raise your stress and lower your HRV. With the most accurate heart rate sensing in a wearable,2 Apple Watch Ultra 4 measures HRV as often as every five minutes and takes background heart rate readings every five seconds — the most frequent sensing ever for Apple Watch. And with the updated Heart Rate app and new watch face complications, you can easily view your readings anytime.

24xmore frequent HRV readings than Ultra 3

Run circles around your data.

Ultra 4 goes the extra mile to ensure that you can precisely track and analyze your running workouts. With real‑time metrics, deeper insights into training and performance, and personalized encouragement, you’ll be motivated to hit your goals like never before.

Wearable AI Assistant

Say hello to Siri AI.

With all-new Siri AI, Apple Watch Ultra 4 can tap into broad world knowledge and your personal context to be even more helpful.4 Using just your voice, you can engage in natural, back-and-forth conversations, brainstorm ideas for workout routines, and get the latest wellness tips with Siri — all from your wrist. And now Audio Intelligence uses the built-in microphone and secure S11 chip in Ultra 4, alongside the power of Apple Intelligence, to make sense of what you hear in a private and secure way.5 Just as Visual Intelligence on iPhone helps you make sense of what you see.

Usage limits may apply.

Great powers come with great privacy.

Made possible by the new S11 chip, Audio Intelligence features are designed to protect your privacy and security at every step. These features do not create or store audio recordings, and raw audio used for processing is completely inaccessible, even to Apple, and is deleted after processing. There is no speaker attribution, and your Live Rewind transcripts and Siri Recaps in the Siri app are end-to-end encrypted through iCloud syncing. You decide whether to opt in to these features, and you control how you use them.5
