The iPhone 15's Action Button, designed for single-function tasks, can be transformed into a multi-app launcher using Apple's Shortcuts app. This workaround allows users to trigger up to eight applications or automations with one press, significantly enhancing the button's utility beyond its default settings. AppleInsider details the process, revealing the button's hidden versatility. Up to eight applications can be launched simultaneously, turning the Action Button into a powerful productivity tool.

The workaround involves creating a Shortcuts folder containing multiple actions and assigning it to the Action Button in System Preferences. This setup leverages the Shortcuts automation app, which Apple has made slightly easier to configure with iOS 18, enabling complex task chaining. The key is launching a folder of shortcuts, which then presents individual options on the screen.

While the Action Button's initial limitation is surprising, given Apple's use of multi-click functionality on AirPods, this method unlocks substantial potential for users seeking streamlined workflows. The process requires navigating the Shortcuts app to create a new folder, populate it with app-launching actions, and then assign the folder to the Action Button via System Settings. Shortcuts automation app is central to this transformation.
