Apple seeded the first developer betas of iOS 27.3 and iPadOS 27.3 on Monday, arriving just a week after iOS 27.2 shipped. The headline change: Apple Intelligence is finally reaching China, where developers on the beta can now switch on a selection of the company's AI features after roughly two years of waiting for a local rollout.

The update also resurrects Apple's redesigned Health app. The overhaul was previewed in September and tested during the iOS 27.2 beta cycle, but Apple pulled it before that update launched. It now returns in 27.3, with the refreshed design built around a longevity focus.

On the wearable side, watchOS 27.3 introduces Audio Intelligence, a set of always-listening AI tools for the latest Apple Watch models. Taken together, the 27.3 cycle looks less like a maintenance release and more like Apple clearing a backlog: a delayed app redesign, a long-stalled regional AI launch, and new on-wrist capabilities all landing in a single beta. Public availability will follow the usual beta track, with registered developers getting first access now.
