Custom iOS 18 Action Button Shortcuts

Apple's iOS 18 significantly expands the capabilities of the Action Button on compatible iPhone models by integrating the new Controls Gallery alongside the Shortcuts app. This update allows users to turn a single physical press into a trigger for advanced automations, contextual menus, and third-party tools. This guide details the most effective custom shortcuts you can configure using the Action Button gallery in iOS 18 to streamline daily tasks, productivity, and device control.

Multi-Action Folder Menus

Instead of assigning a single static function to the button, you can link a shortcut that opens a custom folder menu. When pressed, a dropdown menu appears at the Dynamic Island offering a list of selectable actions, such as:

  • Starting a specific timer or stopwatch.
  • Launching a digital payment card or scanning a QR code.
  • Identifying songs via Shazam.
  • Toggling the flashlight at a specific brightness level.

Instant AI Assistants

With iOS 18, you can bind the Action Button to launch conversational AI interfaces instantly:

  • ChatGPT Voice Mode: Launches the official ChatGPT app directly into live two-way voice conversation.
  • Perplexity or Claude Search: Instantly opens a voice prompt or text query window for deep research without unlocking and searching for the app.

Productivity and Quick Capture

You can configure shortcuts designed to capture thoughts and information without navigating iOS menus:

  • Dictate to Notes: Triggers speech-to-text recording and appends the transcribed text to a designated Apple Notes document.
  • Log Expenses: Prompts an input sheet to log an amount and category, automatically sending the data to a Numbers spreadsheet or budget app.
  • Scan Document: Directly opens the document scanner interface and saves the output to a specified folder in the Files app.

Smart Home Controls

The Shortcuts gallery allows for intricate HomeKit routines that execute based on a single press:

  • Scene Toggles: Activate custom scenes such as "Goodnight" (locking doors, turning off lights, setting the thermostat) or "Arrive Home."
  • Smart Lock Actuation: Unlock or lock a designated door lock without opening the Home app.
  • Garage Door Opener: Triggers your smart garage door opener directly from your pocket.

Contextual and Focus-Based Actions

Using the "If" conditions available within the Shortcuts app, you can create a single smart shortcut that changes its behavior depending on your current status:

  • Work Hours: Opens your task management app (e.g., Reminders, Things, or Notion).
  • Sleep Focus: Mutes all sounds and sets an alarm for the morning.
  • Driving Focus: Sends an automated text with your current ETA to a designated contact.
