iPhone Duo: Turn the Hinge Into an App Launcher

If you're eager to change your screen time habits – like staying off Instagram or reading more books – the iPhone Duo may offer a solution. It's the first iPhone with two screens, and there's a trick that you can use to make it consistently open a specific app whenever you unfold it and look at the bigger display. In the Shortcuts app, there's a new iPhone Duo trigger called "Opened or Closed" that runs an automated action when the device is unfolded or folded.
