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 towards 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 analysing 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 5 minutes and takes background heart rate readings every 5 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.

60xmore frequent background heart rate readings than Ultra 3

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 analyse your running workouts. With real‑time metrics, deeper insights into training and performance, and personalised encouragement, you’ll be motivated to hit your goals like never before.

Monitor your Heart Rate Zones.

Quickly see your exercise intensity level with Heart Rate Zones, which are automatically calculated and personalised using your health data. You can adjust them manually or set up alerts.
Hit the ground running with the Action button.

It’s customisable and gives you quick control over a variety of functions, so you can do things like control a workout, move to your next interval, mark a segment and more. All with extreme precision.
Keep pace with Pacer.

Set specific time and distance goals with Pacer for a running or outdoor cycle workout, and track whether you’re keeping pace.

Never miss a step with an improved step tracker.

Whether you’re out for a leisurely stroll with your coffee in the morning or running on a treadmill at night, Ultra 4 gives you a more accurate step count and distance measurements all day long. And now you can more easily check your step count, right from your watch face.

Subscribers can also follow Routes hands-free with Off-Route Alerts to stay on track. Your workout data automatically syncs with the Fitness app on iPhone.

Extreme staying power.

With optimised, more efficient workout algorithms, Ultra 4 delivers even longer battery life. While providing up to 50 hours of everyday battery use,⁵ it now gives you up to 18 hours of standard workout tracking and up to 45 hours of Max Extended Workout tracking — enough time to complete a 160‑kilometre race.¹

The more health insights you have, the more empowered you are to take actions that will optimise how you perform. With in-depth clinical validation, Apple Watch Ultra 4 provides a fuller picture of your health, so you can stay informed.

Wake up to your sleep score.

Sleep quality is influenced by factors such as sleep duration, bedtime consistency, how often you wake up and time spent in each sleep stage. Sleep score analyses these factors every night and provides a classification and a score. You’ll see how the score is calculated, so you can understand the quality of your sleep and learn how to make it more restorative.
A new read on HRV.

Now you can better understand insights on stress and recovery with HRV in the Vitals app.¹¹ HRV is sampled as often as every 5 minutes, both during the day and night.
Track and understand changes in your cycle.

Cycle Tracking is with you through every stage of your menstrual health journey. Log your cycle and get predictions for your period, fertile window and retrospective ovulation estimates. Cycle Tracking can notify you when your cycle patterns are suggestive of perimenopause as well as provide support during menopause.¹²
Follow your heart more frequently.

Ultra 4 uses high-frequency heart rate tracking to monitor your background heart rate, even when you’re not working out, and surfaces a value every 5 seconds in a new watch face complication.
Measure your blood oxygen. It’s a breathtaking innovation.

The sensor and app in Apple Watch Ultra 3 allow you to take on‑demand readings of your blood oxygen as well as background readings, day and night.¹³

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.³ 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.⁴ Just as Visual Intelligence on iPhone helps you make sense of what you see.

Siri AI is rolling out in English.
Some Audio Intelligence features coming in beta late 2026.
Usage limits may apply.

Revisit conversations in the Siri app.

Ask Siri a question on your iPhone or any other Apple device synced with iCloud, and pick up where you left off on your Apple Watch. Pin conversations and see the same content, including images, across your devices. Here’s to a little more conversation and a lot more Siri.
Siri Recap can summarise your chats to refresh your memory.

Siri Recap transforms your conversations into high-level notes, so you can stay focused and present. Each Siri Recap includes a title, a summary and key points that you can review in the Siri app on your Apple Watch or iPhone. You can turn Siri Recap off or on at any time from Control Centre or choose where and when it takes notes, such as only at work or never at night.¹⁶

Siri Recap coming in beta late 2026.

Live Rewind catches what you missed.

Did someone say something you couldn’t hear in a loud restaurant or share cooking instructions you didn’t quite catch? Just double-click the Digital Crown, and Live Rewind transcribes what was said in the last 15 seconds. You can ask Siri about the content of the transcript or save it to the new Siri app to revisit later.¹⁶

Live Rewind coming in beta late 2026.
Usage limits may apply.
Sound Recognition notifies you when it detects important sounds.

Designed for those who are Deaf or hard of hearing, Sound Recognition can listen for sounds you don’t want to miss, like sirens, alarms, doorbells or a crying baby. You’ll be alerted with a notification on your watch — even when your iPhone isn’t nearby.¹⁷
Shazam can now automatically tell you what song is playing.

Shazam can instantly detect the music playing around you and automatically display the song title and artist’s name on the Music Recognition widget in the Smart Stack — all without a tap. You can also see the song info when you use the Shazam app or Siri. Talk about music to your ears.¹⁸

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.⁴
