Improve accessibility

One slider changes text size across the system and every app that uses Dynamic Type, and Accessibility offers larger sizes still.

Settings > Accessibility > Display & Text Size > Larger Text

Dark Mode switches the system and supporting apps to a dark colour scheme, and can follow a schedule such as sunset to sunrise.

Settings > Display & Brightness > Appearance

The brightness slider sets the base level of the display, and everything else the phone does adjusts around it.

Settings > Display & Brightness > Brightness

The ambient light sensor raises and lowers screen brightness to match your surroundings, and the switch lives under Accessibility rather than Display.

Settings > Accessibility > Display & Text Size > Auto-Brightness

Auto-Correction replaces what it thinks are mistakes as you type, and a newer behaviour underlines corrections so you can tap to undo them.

Settings > General > Keyboard > Auto-Correction

Night Shift shifts the display towards warmer colours on a schedule, usually from sunset to sunrise.

Settings > Display & Brightness > Night Shift

The Action button replaces the Ring and Silent switch and can be set to run the torch, the camera, a Focus, a shortcut or an accessibility feature.

Settings > Action Button

Siri can be summoned by voice, by holding the side button, or by typing, and each method can be turned on separately.

Settings > Apple Intelligence & Siri

A double or triple tap on the back of your iPhone can trigger an action such as a screenshot, the torch, or any shortcut you choose.

Settings > Accessibility > Touch > Back Tap

Zoom magnifies the display, either the whole screen or a movable window, and can apply a filter such as low light or greyscale at the same time.

Settings > Accessibility > Zoom

Reduce Motion replaces the zooming and sliding animations with simple fades, and calms parallax and other moving effects.

Settings > Accessibility > Motion > Reduce Motion

Dictation turns speech into text anywhere a keyboard appears, and on recent iPhones it runs on the device for most languages.

Settings > General > Keyboard > Enable Dictation

Sensors measure the colour of the light around you and adjust the display's white point so white looks like paper rather than a screen.

Settings > Display & Brightness > True Tone

Guided Access locks the iPhone into a single app and can disable parts of the screen, the hardware buttons, and set a time limit.

Settings > Accessibility > Guided Access

Predictive Text offers word suggestions above the keyboard, and Inline Predictions suggests the rest of a sentence in grey as you type.

Settings > General > Keyboard > Predictive

VoiceOver reads the screen aloud and replaces normal touch with a gesture system designed for people who cannot see the display.

Settings > Accessibility > VoiceOver

Colour Filters adjusts the display for colour vision differences, or tints the whole screen a single colour.

Settings > Accessibility > Display & Text Size > Color Filters

System Haptics controls the small taps you feel when using the interface, separately from vibration for calls and alerts.

Settings > Sounds & Haptics > System Haptics

A floating on screen button gives you access to gestures and hardware button functions that would otherwise need a physical press or a multi finger gesture.

Settings > Accessibility > Touch > AssistiveTouch

Siri can read incoming notifications aloud through headphones, and optionally through CarPlay or the speaker.

Settings > Notifications > Announce Notifications

You can define a short code that expands into a longer phrase, and you can use the same feature to stop autocorrect mangling a particular word.

Settings > General > Keyboard > Text Replacement

Triple clicking the side button, or the Home button on older models, turns your chosen accessibility features on and off instantly.

Settings > Accessibility > Accessibility Shortcut

Display Zoom scales the entire interface, so you can choose between larger controls or more content on the screen.

Your iPhone measures headphone volume over time, warns you when exposure is unsafe, and can cap the maximum level.

Settings > Sounds & Haptics > Headphone Safety

Live Captions transcribes audio on your iPhone in real time, including calls, FaceTime, videos and sound around you.

Settings > Accessibility > Live Captions

Magnifier turns the camera into a magnifying glass with zoom, brightness, contrast and colour filters, plus detection modes on capable models.

Settings > Accessibility > Magnifier

Siri says the caller's name aloud before the phone rings properly, so you know whether to answer without looking.

Settings > Apps > Phone > Announce Calls

Colours are adjusted so foreground and background separate more strongly, which makes text and controls easier to pick out.

Settings > Accessibility > Display & Text Size > Increase Contrast

The camera flash blinks when a call or notification arrives, which gives a visible alert when sound and vibration are not enough.

Settings > Accessibility > Audio & Visual > LED Flash for Alerts

Your iPhone can play rain, ocean, stream or noise sounds continuously in the background to mask distractions or help you concentrate.

Settings > Accessibility > Audio & Visual > Background Sounds

A short swipe down at the very bottom edge slides the whole screen down so you can reach the top one handed.

Settings > Accessibility > Touch > Reachability

Closed captions and subtitles for the deaf and hard of hearing can be turned on system wide, with a custom style for size, colour and background.

Settings > Accessibility > Subtitles & Captioning

Mono Audio plays the same signal in both channels, and the balance slider shifts volume towards one ear.

Settings > Accessibility > Audio & Visual

Menus, Control Centre and other frosted panels become solid, which raises contrast and makes text easier to read.

Settings > Accessibility > Display & Text Size > Reduce Transparency

This lowers the intensity of bright colours beyond what the brightness slider can reach, which helps in a very dark room.

Settings > Accessibility > Display & Text Size > Reduce White Point

Speak Selection reads highlighted text aloud, and Speak Screen reads an entire page after a two finger swipe down from the top.

Settings > Accessibility > Spoken Content

Animated dots around the edge of the screen move with the vehicle, which reduces the mismatch between what you see and what you feel.

Settings > Accessibility > Motion > Show Vehicle Motion Cues

Voice Control lets you tap, scroll, type and navigate entirely by voice, with numbered or named overlays showing what you can say.

Settings > Accessibility > Voice Control

On the iPhone Duo a compatible Apple Pencil can be used on the inner display for handwriting, drawing and marking up documents.

Settings > Apple Pencil

Smart Invert reverses the display colours but leaves images, video and apps that already use a dark style alone.

Settings > Accessibility > Display & Text Size > Smart Invert

Your iPhone can listen continuously for specific sounds such as a smoke alarm, a doorbell or a baby crying, and alert you when it hears one.

Settings > Accessibility > Sound Recognition

Assistive Access replaces the entire interface with large buttons, high contrast and a small set of apps, designed for people with cognitive disabilities.

Settings > Accessibility > Assistive Access

Made for iPhone hearing aids pair here, and the same screen holds hearing aid compatibility mode and audio routing for hearing devices.

Settings > Accessibility > Hearing Devices

You can make touch and hold menus appear faster or slower, which helps if they either never appear or appear when you did not want them.

Settings > Accessibility > Touch > Haptic Touch

The keyboard can be shifted to the left or right so every key is within one thumb's reach.

Settings > General > Keyboard > One Handed Keyboard

Supported headphones can be tuned to amplify quiet sounds and adjust frequencies to match your hearing.

You can set how long a touch must last before it counts, ignore repeated touches, and choose whether the first or last place you touch is used.

Settings > Accessibility > Touch > Touch Accommodations

Text that acts as a button gets an underline or a shape, so you can tell what is tappable.

Settings > Accessibility > Display & Text Size > Button Shapes

You can set larger text, bolder text, reduced motion, button shapes and more for one app without changing the rest of the system.

Settings > Accessibility > Per-App Settings

The front camera follows where you are looking, and holding your gaze on an item selects it.

Settings > Accessibility > Eye Tracking

Switch Control scans through items on screen and lets you select them with an external switch, the screen itself, or head movement detected by the camera.
