Everyone who has used the iPhone for even just a few minutes knows that the Home button, the only button on the iPhone’s front, is crucial. But few know just how many things the Home button can do. Here’s a quick overview of six Home button functions. Our list concludes with a little-known yet powerful option for our readers– the accessibility shortcut!

Accessing Siri

Holding down the Home button will silently launch Apple’s digital assistant, Siri. (“What Can I Help You With?” reads your screen.) This function may also be changed to access Voice Control (Settings > Home button).


Double-clicking the Home button reveals all running apps in the multitasking manager. Scroll and select one to use, or swipe upwards one by one to close.

Dismissing Apps

If Control Center or any app is open, you can dismiss it with a single click of the Home button.

Touch ID

On iPhone 5S through 8, the Home button is a fingerprint scanner that makes these devices more secure. Touch ID is used to unlock the iPhone, to enter passcodes and passwords for purchases at the iTunes and App Stores, and for use with Apple Pay.


Included with the iPhone 6 series and newer, iPhone offers users a feature called “Reachability.” Because these phones have large screens, it can be hard for some users to reach from one side to the other using one hand. Reachability solves that problem by pulling the top of the screen down to the center to make it easy to navigate. Users can access Reachability by double-tapping the Home button (not clicking; just a light tap as with tapping an icon).

Accessibility Short Cut

Here’s a feature that is less commonly known: a short cut to accessibility! Want a fast way to access color filters? Zoom? Switch control? iPhone allows users to program the Home button’s triple-click (not tap) function. Here’s how:

  1. Go to the Setting app.
  2. Tap General > Accessibility > Accessibility Shortcut (the last option).
  3. Choose from the following actions:
    • Assistive Touch
    • Classic Invert Colors
    • Color Filters
    • Reduce White Point
    • VoiceOver
    • Smart Invert Colors
    • Switch Control
    • VoiceOver
    • Zoom

By default, the Home button only responds to single or double clicks. The triple-click is activated by the user. Note that more than one function may also be selected and a menu will display for choosing what you want to activate.
