If you’re someone who doesn’t have any specific reasons to go there, you may have never explored the Accessibility settings on your Mac, iPhone, or iPad. While it’s true that those settings are there primarily for people who have special physical needs to modify how a device’s interface works, the fact is, many people who don’t consider themselves in need of any sort of accommodation can find something of value in these settings.

Accessibility has become a place where Apple buries some specific, nitpicky details about how its devices behave–and that’s why you should take a stroll through those settings sometime just to see if they solve problems you didn’t even realize were solvable. Here are some of my favorites:

iOS accessibility

In iOS, Accessibility settings are located in the Settings app. First tap General, then tap Acessibility.

Zoom. If your eyes aren’t what they once were, consider turning on the Zoom setting, which lets you magnify the iPhone screen with a gesture–namely, double-tapping three fingers.

Magnifier. This setting was just pointed out to me this past weekend at a presentation I was giving to a group of mostly retired people. Activated with a triple-click of the home button, Magnifier looks very much like the interface to the iPhone’s camera. But there’s an explicit zoom slider and the shutter button is there not to take a picture, but to stabilize the image of whatever you’re magnifying so you can study it. If you’re frustrated by not being able to read incredibly small type, Magnifier can be the solution.

Color Filters. Located within the Display Accommodations menu, Color Filters let people who are color blind differentiate between colors. As someone who is red-green color blind, I’ve explored these features before. I ended up deciding to leave these settings off because they made my iPhone screen aesthetically unpleasing, but everyone’s mileage will vary. There are a variety of settings for different forms of color deficiency.

Text visibility. A series of settings let you adjust text on your iOS device so it’s more readable. If you turn on the Larger Text option, you can make the text in any app that supports Apple’s Dynamic Type feature quite large. You can also turn on Bold Text to make everything that much more readable, though this feature requires a restart.

Button Shapes. If you’ve been frustrated by the fact that so many iOS buttons are invisible–they look like colored text, but there’s no button there–you can solve this by turning on Button Shapes. All the buttons will gain a gray background shape when this feature is turned on.
