Apple rolls out iOS 27 with a long‑awaited overhaul of its Calendar app. The highlight is Smart Event Details, a natural‑language parser powered by Apple Intelligence that fills title, time, location and invitees as you type. It works for both new and existing entries, cutting manual edits.

Design tweaks replace the old list view with a card overlay that shows event details alongside new icons for each option. iCloud calendars finally gain a busy/free toggle, matching Google and other third‑party services. The update also adds extra‑large widgets for List and Up Next, letting power users see more appointments on the upcoming iPhone Ultra screen on larger displays.

Siri receives a suite of AI upgrades that make it more context‑aware when managing calendars. A new visual‑intelligence button in the event creation screen lets users scan a flyer with the Camera app, and Siri populates the event automatically. Together, these tools turn Calendar into a more proactive assistant for busy professionals across all iPhone models.
