Apple is about to release a surprise new feature for the iPhone (and likely the iPad and Mac) to help you invite people to parties and other events, according to a new report, as part of a revamp to Apples calendar app. And its coming soon, for employees to test, it seems.A new app could be coming to the iPhone soon. 2025 Bloomberg Finance LPAs early as this coming week, Apple plans to introduce a new iCloud-based service dubbed Confetti internally. As the festive code name implies, the service offers a new way to invite people to parties, functions and meetings, according to Bloombergs Mark Gurman in his latest Power On newsletter.Note that Gurman refers to it as a service, so its possible that it wont be a standalone app but rather an enhanced part of the Calendar app or iMessage, perhaps.For years, Apple has been seeking to revamp its calendar app and this new initiative could be the beginning of a broader effort. The release is tied to iOS 18.3, which just started rolling out last Monday, Gurman goes on.This chimes with a report from 9to5Mac in January which referred to something called Invites, discovered in the iOS 18.3 code, which suggests that the Invites app will integrate with iCloud and will even have a web version on iCloud.com. The new app also integrates with a new iOS 18 daemon called GroupKit, which manages database models for groups of people. This daemon has been present since the first release of iOS 18.0 and hasnt been used by any Apple apps so far.MORE FOR YOUIt seems that it will work by showing a list of the people invited to that event and which ones have confirmed their attendance. It could be that Apple has plans to integrate it with other parts of the system (such as a mini iMessage app). Presumably, the app will have a more fun interface than what the Calendar app currently provides for inviting someone to an event, 9to5Mac goes on.Whats most intriguing is that Apple has never dropped the slightest hint that its working on this update, which could mean it wont appear. But Gurmans belief is that it might be just days away from employee testing, which could mean public release will follow soon after. More details as they emerge.
