Any Apple device is equipped with assistive technologies that make the gadget accessible to everyone, including people with disabilities. All this useful functionality is collected in the "Accessibility" section on Mac, iPhone and iPad.

Even if you don't have a special reason to modify the device interface to suit your needs, in this section you will find many interesting features that will help you solve problems that previously seemed insurmountable.
Accessibility on Mac
macOS is a more flexible operating system than iOS, so there is no need for so many special features. However, under System Preferences -> Accessibility in macOS, there are still some interesting possibilities.

This functionality is available on both older Mac computers and the latest APPLE MACBOOK PRO MLUQ2 models equipped with a Touch Bar.
Scaling

This function is useful if you need to draw attention to any part of the screen during a presentation or lecture. With a keyboard shortcut, you can zoom in on the desired area on the display, and with the Ctrl key held down, you can change the zoom using trackpad or Magic Mouse gestures.
Monitor

The Monitor section in macOS offers a number of options similar to those of iOS. Enabling some options (Reduce Motion, Reduce Transparency) may have a positive effect on system performance.
Mouse & Trackpad panel

macOS lets you turn off the built-in trackpad when using a mouse to control your Mac. In addition, here you can configure the mouse cursor control from the keyboard.
Screen flash in the Audio section
In order to grab the user's attention, the Mac can use a visual instead of a sound signal - a screen flash. It will be automatically triggered in all applications that use a beep. To turn on the flash, you need to check the box "Screen flash at warning sound".

IOS Accessibility

In order to access the section, go to "Settings" -> "General" -> "Accessibility".
Magnification

If you want to zoom in on the iPhone screen, use the Zoom function. To do this, activate the functionality in the settings and, if necessary, enlarge the interface, double-tap the screen with three fingers.

Magnifier function

The Digital Magnifying Glass became available with the release of iOS 10. The feature is activated by triple-pressing the Home button and looks like the iPhone camera interface, allowing you to zoom in for a closer look. If you do not want to strain your vision by peering into too small text, a magnifying glass will help you solve the problem.

Color filters

In the Display Adaptation menu, there is a Filters option that allows people with various forms of color blindness and other visual impairments to invert colors, lower white balance, or display only certain shades.
Convenient text size

If the font in iOS or other applications is too small for you and you have to strain your eyes to read the text, you can choose a more appropriate font (large or bold) in Accessibility.

Button shape

In iOS, there are no separately drawn buttons, they are replaced with simple labels, which is not very convenient. If desired, users can change the shape of the buttons, making them clearer and more reminiscent of the actual buttons. To do this, turn on the "Button shape" item and all buttons will have a gray background.
Increase contrast and decrease motion

iOS allows you to adjust not only the brightness of the screen, but also its contrast. In the menu "Increase Contrast" there is an option "Decrease transparency", which will turn off the effect of 3D elements of iOS. Deactivating the "Reduce Motion" option will disable overly "fluffy" animations when switching between applications.

Shake to Undo

This feature allows you to delete already typed text by simply shaking your iPhone and iPad. As a rule, this iOS feature only hinders users. You can disable the function by opening the Shake to Cancel menu and toggling the toggle switch to the off position.
Vibration

In Universal Access, you can turn off vibration for incoming calls, SMS messages, etc.
One-handed mode

This mode allows you to perform all actions on the large screen with one hand. The function can be activated by accidentally double tapping on the Home button (the home screen will go down so that the upper interface elements are within the reach of the thumb). To avoid such situations, the mode can be disabled.
Mono Audio Mode

Mono Audio converts the left and right stereo channels to monaural and plays back on both channels. The mono balance can be adjusted to increase the volume of the right or left channel. To enable / disable the mode, select "Accessibility" -> "Mono-audio".
Guide access

The Guided Access function (example of use) limits the operation of the device to one application. This mode can be useful in various cases, for example, if parents want their child to just play the game, and not send messages.
