Apple Watch Series 12 and Ultra 4 Leak Hints at Four Major Upgrades

Recent discoveries in Apple’s beta software suggest that the upcoming Apple Watch Series 12 and Apple Watch Ultra 4 could bring several useful improvements. While Apple has not officially announced these features, the findings point to upgrades focused on health tracking, fitness, heart monitoring, and storage.

If these leaks are accurate, the next generation of Apple Watches may offer a better experience for both everyday users and fitness enthusiasts.

New Readiness App May Help Monitor Recovery

One of the most interesting discoveries is a possible Readiness app. It appears to be separate from Apple’s existing Vitals app and is referenced in the latest watchOS and iOS beta software.

Although the app is not available for testing yet, its name suggests that it could help users understand how prepared their body is for exercise. Instead of only showing health data, it may provide recovery insights based on recent activity and overall condition.

Possible features include:

• Recovery status after workouts
• Daily readiness score for training
• More detailed fitness insights
• A dedicated space for recovery information separate from the Vitals app

If introduced, this feature could help users make smarter decisions about when to train and when to rest.

Strength Workouts Could Become More Detailed

Apple also appears to be working on better tracking for strength training.

Current workout records mainly save an entire session as one activity. The updated system could store detailed information for every exercise set, giving users a more complete workout history.

The new tracking system may include:

• Individual workout sets
• Number of repetitions
• Weight used
• Equipment used
• Left or right body side involved
• Time spent on each set

These improvements could make strength training records more accurate and useful for tracking progress over time.

Updated Sensor May Improve Heart Rate Accuracy

Another leak points to a new optical sensor system that could improve heart rate monitoring.

The beta code mentions updated filtering methods and different sensor settings that adjust based on how the watch is worn on the wrist. These changes may help the watch detect pulse signals more accurately, especially when readings are difficult to capture.

Apple has not confirmed whether this new sensor will appear in the Series 12, Ultra 4, or both models.

Storage Could Increase to 128GB

The leaked software also suggests a possible storage upgrade.

References linked to Apple’s upcoming processor indicate support for a storage configuration that could provide 128GB of internal storage. Current Apple Watch models offer up to 64GB, so this would double the available space.

Additional storage could benefit users who install many apps, download music or podcasts, or use future watch features that require more local storage.

Researcher Behind the Leak

The information was reportedly discovered by a forum researcher known as pdfu, who has previously found references to unreleased Apple products in beta software. Earlier discoveries included possible game controllers and hidden HomePod features before their official announcements.

As with any pre-release information, these findings should be treated as rumors until Apple makes an official announcement.

Final Thoughts

The latest beta software hints that the Apple Watch Series 12 and Apple Watch Ultra 4 could introduce meaningful improvements. A dedicated recovery app, more advanced strength workout tracking, improved heart rate sensing, and larger storage are among the most notable possibilities.

Since Apple has not officially confirmed these features, it is best to wait for the company’s launch event for complete and accurate details.
