The app is not yet in the beta, so its exact function is unconfirmed, but it is expected to tell users how recovered they are and whether they are ready for exercise. Strength training recording is also enhanced, allowing per-set logs of reps, weight, equipment, body part, and time. The storage capacity is rumored to double to 128GB, based on a setting found in the watchOS 27 beta for the chip T8320. Bloomberg's Mark Gurman previously reported that the new Apple Watch would strengthen health and fitness features. The announcement was made at the event held at 2:00 AM Japan time on September 10, 2026.","whyItMatters":"The inclusion of a 128GB storage setting in the watchOS 27 beta, while the current models have 64GB, suggests Apple is preparing a significant capacity upgrade, which could enable more on-device health data and apps.","webCardHtml":"\u003cp\u003e\u003c/p\u003e\u003cul\u003e\n  \u003cli\u003eGAME Watch and GIGAZINE both frame the event around the iPhone announcements, but only ASCII.jp\u0026#39;s \u0026#34;Apple Rumor Information Bureau\u0026#34; column details the four beta findings ahead of the announcement.\u003c/li\u003e\n  \u003cli\u003eThe beta evidence comes from a forum user named \u0026#34;pdfu\u0026#34; on MacRumors, who examined watchOS 27 and iOS 27 developer builds and found the clues.\u003c/li\u003e\n  \u003cli\u003eOn the revamped heart rate sensor, the \u0026#34;noise\u0026#34; value is about 10 to 20 percent smaller than before, and the sensor can switch measurement method based on which wrist the watch is worn on and the Digital Crown\u0026#39;s orientation.\u003c/li\u003e\n  \u003cli\u003eStrength training logs are described as working like a gym training log, replacing the older, simpler record of only total minutes of strength training.\u003c/li\u003e\n  \u003cli\u003eThe 128GB setting is only for the chip \u0026#34;T8320,\u0026#34; and watchOS 26 included both 64GB and 128GB options while the watchOS 27 beta reportedly includes only the 128GB one.\u003c/li\u003e\n  \u003cli\u003eThe Readiness app is placed next to the Workout app in the default watchOS 27 home screen layout, but is not yet in the beta, so its contents are unconfirmed.\u003c/li\u003e\n  \u003cli\u003eBloomberg\u0026#39;s Mark Gurman reported in August that the new Apple Watch would strengthen health and fitness features, ahead of the September 10 event.\u003c/li\u003e\n\u003c/ul\u003e\u003cp\u003e\u003c/p\u003e","blueskyPost":"Apple Watch Series 12 and Ultra 4 are here, and the watchOS 27 beta hints at a 128GB storage option, doubling the current 64GB.
