Apple has released the fourth beta of watchOS 26.4 for testing purposes. The update is currently limited to developers, though public beta testers will receive the beta access in a matter of time. The incremental upgrade comes out a week after the third beta. The update is expected to bring several new features and changes to the Apple Watch.
Apple plants the watchOS 26.4 beta 4 update to the compatible watches with 23T5236a build number. The gradual upgrade for testers is 560MB in download size. The update is available to everyone running on watchOS 26 or newer. It is a free upgrade, so if you’re a developer, you can easily update your Apple Watch to the latest watchOS 26.4 beta.
As usual, Apple didn’t mention any changes in the watchOS 26.4 upgrade. Despite this, iOS 26.4 beta users have discovered notable additions for Apple Watch with watchOS 26.4: a revamped watch face gallery with downloadable packs, end-to-end encrypted RCS messaging in beta, a new “Urgent” Reminders smart list with auto-alarm, Indian English localization support, and further refinements.
