As iPhone displays have gotten larger, the days when using only one finger to perform most tasks are generally over. However, it's still possible, at least in some respects, with Reachability. When activated, this accessibility feature lets you reach items at the top of the mobile device by swiping down on the screen's bottom edge to bring the top into reach. Here's how to use it on iOS 15 and all the best iPhones.

What is Reachability?

Reachability is a built-in iOS feature that lowers the top half of the screen so buttons and other on-screen objects are within easy reach of your thumb. For many folks, these will be top navigation buttons while using their phones one-handed.

It is available regardless of where you are on your mobile device and is super useful when using your phone with one hand.

How to enable Reachability

  1. Launch Settings from your Home screen.
  2. Scroll down and tap Accessibility.
