Accessibility features let you use your phone, computer, or app the way that works for your body and mind

An accessibility feature is a built-in tool that changes how your device or app works so you can use it more easily. These aren't add-ons you have to buy — they're already there. They might enlarge text, read words aloud, let you control your screen with your voice, slow down animations, or change colors to reduce glare. The point is simple: the same device works differently for different people, depending on what you need.

Most phones, computers, and major apps have accessibility features because laws in many countries require them. But they exist because they're useful. Someone with arthritis might use voice control to avoid typing. Someone who is colorblind might switch to a high-contrast display. Someone with dyslexia might turn on a reading guide that highlights words as they're read aloud. Someone who is deaf might turn on captions. Someone with tremors might enable sticky keys so they don't have to hold down multiple keys at once.

The features are there whether you need them for a disability, a temporary injury, or just because you prefer to use your device that way. You don't have to explain or prove anything to turn them on.

Key Takeaways

  • Accessibility features are built into most devices and apps at no extra cost, and you turn them on in your device settings or app preferences.
  • Common features include text enlargement, voice control, screen readers that read text aloud, captions, high-contrast colors, and adjustments to animation and timing.
  • You don't need to justify using them — they're there for anyone who finds them useful, whether for a disability, injury, or personal preference.
  • Different devices and apps have different features available, so it's worth checking what your specific phone, computer, or software offers.
  • Many accessibility features also help in situations where you don't have a disability — captions help in noisy places, large text helps in bright sunlight, and voice control helps when your hands are full.

Where to find accessibility features on your device

On an iPhone or iPad, go to Settings, then Accessibility. You'll see categories like Vision, Hearing, Mobility, and Cognitive. On an Android phone, go to Settings, then Accessibility (the name and location vary slightly by manufacturer, but it's always in Settings). On a Windows computer, go to Settings, then Ease of Access. On a Mac, go to System Settings, then Accessibility.

Once you're in the accessibility menu, you can turn features on and off individually. You don't have to turn on everything at once — try one thing, see if it helps, and add more if you want. Most devices let you adjust how strong each feature is. You can make text slightly larger or much larger. You can slow down animations a little or a lot. You can turn on captions just for videos, or for everything that has sound.

Apps sometimes have their own accessibility settings separate from your device settings. Check the app's settings menu or preferences — often under a gear icon or three horizontal lines — to see what's available there.

Vision-related features: text, color, and screen reading

If you have low vision or just find small text hard to read, you can enlarge text across your whole device or in specific apps. Most devices let you make text anywhere from slightly larger to very large. You can also increase the contrast between text and background — switching to white text on black, or black text on white, depending on what's easier for your eyes.

A screen reader is a feature that reads text aloud as you move your finger or cursor around the screen. On iPhones and iPads, it's called VoiceOver. On Android, it's TalkBack. On Windows, it's Narrator. On Mac, it's VoiceOver. Screen readers work with most apps, though some apps are built better for them than others. When you turn on a screen reader, you navigate by tapping or swiping in specific patterns — it takes practice, but once you learn it, you can use your device without looking at the screen.

You can also reduce motion and flashing. Some people find animations — like when an app opens or a page scrolls — uncomfortable or disorienting. Turning on "Reduce Motion" slows these down or removes them. If you're sensitive to flashing lights, you can turn off flashing in videos and notifications.

Hearing-related features: captions and sound alerts

Captions show the words being spoken in videos, calls, and apps. Most devices have a setting to turn on captions by default, so they appear automatically in any app that supports them. You can usually adjust the size and style of the caption text. Some apps let you choose the background color and transparency too.

If you're deaf or hard of hearing, you can also turn on visual alerts — a flash of light or a visual notification instead of a sound when someone calls, texts, or sends a notification. Some devices let you set different visual patterns for different types of alerts so you can tell what's happening without looking at the screen.

Mono audio combines left and right stereo channels into one, which helps if you have hearing loss in one ear. Some devices also let you adjust the balance between left and right speakers.

Mobility features: voice control and one-handed use

If typing or tapping is difficult, you can use your voice to control your device. On iPhones and iPads, it's called Voice Control. On Android, it's Voice Access. On Windows, it's Voice Typing. You speak commands like "open Mail" or "tap the blue button" and the device does it. You can also dictate text instead of typing it — most devices have a microphone button on the keyboard that lets you speak instead of type.

Sticky keys let you press modifier keys (like Shift, Control, or Alt) once instead of holding them down while you press another key. This helps if you have limited hand strength or use one hand. Switch Control lets you navigate your device using a single button or switch — useful if you can't use a touchscreen or keyboard in the usual way.

One-handed keyboard mode shrinks the keyboard to one side of the screen so you can reach all the keys with one hand. Some devices also let you enlarge touch targets — the buttons and links you tap — so they're easier to hit accurately.

Cognitive and learning features: reading guides and simplified interfaces

A reading guide highlights the line of text being read aloud, which helps you follow along if you have dyslexia, ADHD, or just prefer to read with audio support. Some devices let you adjust the color and thickness of the highlight. You can also turn on word spacing and letter spacing to make text less crowded.

Focus mode (or Do Not Disturb) removes notifications and distractions so you can concentrate on one task. Some apps have a simplified mode that hides advanced features and shows only the basics. You can also turn off animations and transitions, which some people find distracting.

If you find it hard to remember passwords or fill out forms, your device can store and auto-fill passwords, addresses, and payment information. This is both an accessibility feature and a convenience feature.

Accessibility features that help everyone

Many accessibility features are useful even if you don't have a disability. Captions help you watch videos in a noisy place or when you can't use sound. Large text helps in bright sunlight. Voice control helps when your hands are full or dirty. Dark mode reduces eye strain in low light. Reducing motion helps if you get motion sickness from animations.

This is why accessibility features are worth exploring even if you've never thought of yourself as needing them. You might find that turning on captions makes you enjoy shows more. You might discover that dark mode makes your device more comfortable to use at night. You might realize that slowing down animations makes your device feel less overwhelming.

Frequently Asked Questions

Will turning on accessibility features slow down my device?

Most accessibility features have little to no impact on speed. Screen readers and voice control use your device's existing processing power. Some features like animations and visual effects actually use less power when turned off, so they might make your device slightly faster.

Can I turn accessibility features on and off quickly?

Yes. On most devices, you can add accessibility shortcuts to your home screen or quick settings menu. On iPhones, you can triple-tap the home button to toggle VoiceOver on and off. On Android, you can add accessibility shortcuts to your quick settings panel. On computers, you can usually set keyboard shortcuts for features you use often.

Do accessibility features work in all apps?

Most do, but it depends on how well the app is built. Large text and captions work in nearly all apps. Screen readers work in most apps, but some apps aren't designed with screen readers in mind and can be harder to use. If an app doesn't work well with the accessibility features you need, you can leave a review in the app store mentioning this — developers do read them.

Can I use multiple accessibility features at the same time?

Yes. You can turn on as many features as you need. For example, you could use large text, high contrast, captions, and a screen reader all at once. Start with one or two and add more if you want.

Are accessibility features private, or does anyone know I'm using them?

They're private. Turning on accessibility features doesn't send information to anyone or appear in your activity. Only you and anyone physically near your device can see that you're using them.
