Set Your Action Button to Open Magnifier

Magnifier is one of the most underrated of the built-in iPhone tools, especially if your vision isn’t as good as it used to be. And the best part is that the Action button is a great way to make it easier to use. Apple lets you assign the button to a group of accessibility features, including the Magnifier, so you can turn your phone into a fast reading and inspection tool without digging through your apps first.

That’s useful in more situations than most people expect. Restaurant menus, medication labels, product packaging, serial numbers, appliance text, and tiny printed instructions are all things that can suddenly become annoying to read when you’re in a rush or you forgot your reading glasses. Magnifier solves that problem quickly, and giving it a hardware shortcut makes it easier to use it.
