\t\"\"<\/p>\n

Apple Watch Ultra 4 and Series 12<\/a> will be unveiled tomorrow, and a last-minute leak may reveal new features coming in watchOS 27 for the latest models and more.<\/p>\n

New Apple Watch features could include Readiness app, richer strength training options, more<\/p>\n

\"\"<\/p>\n

In the last few days, X user pdfu<\/a> has posted several discoveries from Apple code that hadn\u2019t previously been revealed.<\/p>\n

He shared evidence<\/a> that HomePod will gain surround sound and \u201cparty mode\u201d features, and also detailed several pro-focused photography features reportedly<\/a> coming to iOS 27\u2019s Camera app.<\/p>\n

More recently, pdfu has also posted an X article<\/a> detailing several Apple Watch changes uncovered in watchOS 27 code.<\/p>\n

His findings relate to four main features:<\/p>\n

New Readiness app<\/p>\n

Richer strength workouts<\/p>\n

New optical-sensing system for Apple Watch\u200b<\/p>\n

Hints about 128GB of storage<\/p>\n

Regarding the Readiness app, pdfu writes:<\/p>\n

The watchOS 27 launcher includes it in its default Home Screen layout ordering immediately after the Workout app. The Watch companion app on iOS 27 also references the same Readiness app in its implementation for arranging apps.<\/p>\n

No further specifics are shared, but the app\u2019s name combined with its placement next to Workout suggests functionality similar to what competing third-party wearables like the Oura Ring offer.<\/p>\n

Update: Mark Gurman says<\/a> Readiness will be a variant of the Vitals app.<\/p>\n

I do expect Apple to announce a new Readiness app for the Watch tomorrow, as a variant of the Vitals app. The idea is to better compete with software from Whoop & Oura. There\u2019s also the revamped heart rate sensing. More on what to expect from Apple \u2013 https:\/\/t.co\/iLkhZBmHz0<\/a><\/p>\n

\u2014 Mark Gurman (@markgurman) September 8, 2026<\/a><\/p>\n

Regarding strength workouts, it sounds like Apple may be building a full-featured competitor to other strength training apps, but right inside Workout. For example, \u201cThe new implementation can describe individual sets and store repetition counts, weight, equipment, body side, and duration for each set.\u201d<\/p>\n

The new optical-sensing system corroborates rumors<\/a> that Apple Watch Ultra 4 and perhaps Series 12 will boast a ton of internal sensor changes. Finally, there\u2019s evidence that the new S-class chip for Apple\u2019s latest Watch models will offer 128GB of storage.<\/p>\n

Some of these changes seem tied to new hardware while others, like the Readiness app, will hopefully be available in watchOS 27 for older models too.<\/p>\n
