You can make it easier to read text on iPhone by increasing its size or making it bold. You can set a single preferred text size for supported apps, like Calendar, Mail, Messages, and Notes. For additional text sizes, there’s Larger Accessibility Sizes, too.

Make text bigger and bolder

For all supported apps, including Settings, Notes, Messages, Mail, Calendar, and more, you can choose a single preferred text size and turn on bold text.

1. Open Settings, tap Accessibility, and then tap Display & Text Size.
2. Do any of the following:
   • Make text bigger: Tap Larger Text and drag the slider to adjust the text size.

     For additional text sizes, turn on Larger Accessibility Sizes.

   • Make text heavier: Turn on Bold Text.

Quick tip: You can change text size without leaving an app. Open Control Center and adjust the Text Size slider . If the slider isn’t there, tap the Add button in the top-left corner and tap Add a Control, then tap the Text Size control.

Turning on Display Zoom to increase the size of text also enlarges interface elements like icons and buttons.

You can also temporarily hover on text to see it larger, change display colors on iPhone to make it easier to see what’s onscreen or zoom in on the screen.

You can remotely control your other Apple devices without adjusting any switch connections. With Platform Switching, you can navigate your iPad, Mac, or Apple TV 4K using the same switch that you use to control your iPhone.

All your devices need to be on the same Wi-Fi network and signed in with the same Apple Account, with Switch Control turned on for each one. And you can disconnect at any time from the Devices menu on the connected device.

1. Connect your devices to the same Wi-Fi network.
2. Sign in with the same Apple Account on all your devices.
3. Set up and turn on Switch Control on iPhone. Turn on Switch Control for the others: iPad, Mac, or Apple TV 4K.
4. Use the switch to open the Scanner menu.
5. Choose Device, choose Use Other Device, and then choose Connect.

To remove control from your iPhone, choose Devices on the connected device, then choose Disconnect.

You can use Switch Control on iPhone to select items, perform actions, and more. Once you set up and turn on Switch Control, you can use item mode to select items and perform actions, or use the gliding cursor, head tracking, or eye tracking to control the cursor on the screen.

• Item mode: The cursor sequentially highlights items or groups of items. This is the default method when you first turn on Switch Control and whenever the Scanner menu appears.
• Gliding cursor: You select a point on the screen using scanning crosshairs. This method is useful when you need to select a specific point, such as in Maps, or on a screen with many items.
• Head tracking: You can move your head (detected by the front-facing camera) to control the cursor on the screen.
• Eye tracking: You can move your eyes (detected by the front-facing camera) to control the cursor on the screen.

When the cursor is on the item you want, the Scanner menu opens to show the available actions such as tap, scroll, control the volume, and more.

Use item mode to select items and perform actions

1. Depending on the scanning style you’re using, do one of the following:
   • If using Auto Scanning: Watch or listen as groups of items are sequentially highlighted.
   • If using Manual Scanning: Activate your Move to Next Item switch to navigate through the groups of items on the screen.
   • If using Single Switch Step Scanning: Activate your Move to Next Item switch to navigate through the groups of items on the screen.
2. When the group you want is highlighted, do one of the following:
   • If using Auto Scanning: Activate your Select Item switch.
   • If using Manual Scanning: Activate your Select Item switch.
   • If using Single Switch Step Scanning: Wait until the current group is automatically selected.
3. Repeat steps 1 and 2 to scan and select an item within the group.
4. Repeat steps 1 and 2 to scan and choose an action in the Scanner menu. The dots at the bottom of the menu provide more options.

Once the original item is highlighted and every icon in the menu is dimmed, activating your Select Item switch closes the Scanner menu without choosing an action.

Use the Gliding Cursor to select a point

By default, Switch Control starts in item mode, though you can use the Gliding Cursor instead.

1. Do either of the following:
   • Go to Settings > Accessibility > Switch Control > Switch Control Mode > then select Gliding Cursor.
   • Use item mode to select any item, then choose Gliding Cursor (in the Scanner menu).

   To position the vertical crosshair, activate your Select Item switch when the wide vertical band is over the item you want.

2. Activate your Select Item switch again when the fine vertical line is over the item.
3. To position the horizontal crosshair, activate your Select Item switch when the wide horizontal band is over the item you want.
4. Activate your Select Item switch again when the fine horizontal line is over the item.
5. In the Scanner menu, select the action you want and then activate your Select Item switch.

To return to item mode, open the Scanner menu, then choose Item Mode.
