Fantastical 4.2 launches alongside iOS 27 and macOS 27 Golden Gate with deep Siri AI integration, allowing users to ask Siri to check calendars, create events, or modify appointments. Flexibits says you can query your schedule for a specific date like October 5 and then move meetings if timing conflicts arise, with conversations referenceable later in the Siri app. The update introduces an extra-tall widget size for Event List and Event List + Calendar widgets on iOS and macOS, providing more visibility for upcoming events.

On Mac, Fantastical receives a refreshed Liquid Glass interface for macOS 27 while restoring the familiar sidebar appearance. Cardhop 2.5 also releases today with larger Quick Actions and Celebrations widgets supporting extra-tall layouts on iOS and macOS, plus extra-wide options on iPadOS, macOS, and visionOS. Both Fantastical 4.2 and Cardhop 2.5 are available now, with further details in Flexibits' announcement.

Apple plans to release iOS 27, macOS 27 Golden Gate, and more at 10 am PT/1 pm ET.
