1. Use your iPhone to measure nearby objects

The Measure App (available on iOS 12 and above) uses your mobile’s rear camera to measure real-world objects. Your phone can automatically detect the dimensions of a rectangular object, or you can manually tap the screen to set start and end points.

To try it yourself, open the Measure app and move the iPhone camera slowly to scan a nearby object. For automatic measurements, the iPhone will detect the edge of the object and frame it in a white box – tap the white box or select the + symbol to see the dimensions.

You can take a picture of the measurement with the camera shutter.

If you’re taking a manual measurement, align the on-screen dot at the center of your screen with the point where you want to start measuring, then tap Add. Slowly move your phone to the end point, then hit the + symbol to see the measured length.

Again, use the camera shutter button to save the results. Otherwise, find Clear to start again.

Ruler view

On iPhones equipped with a LiDAR Scanner (iPhone 12 Pro swear 12 Pro Max, iPhone 13 Pro swear 13 Pro Max, iPhone 14 Pro swear 14 Pro Max), you can measure the height and straight edges of furniture and countertops.

These same models also support Ruler view, which means you move the iPhone closer to the measurement line until it transforms into a ruler.

2. Translate text using the Camera app

If you’re looking at text written in an unfamiliar language, you can use your phone’s camera to translate it. Simply open the Camera app on your iPhone and hold the phone still while it scans the text.

Once your mobile recognizes the text, you’ll see yellow lines circle the area on-screen. In the bottom-right corner of your screen, tap the Scan symbol – this will isolate the text and magnify it as a still image. Finally, click Translate in the bottom-left corner of your display to see the results.

Translate text from photos in your image library

Perhaps you have a picture in your image library that you’d like translated. If so, just run through these steps:

  1. Open up the Translate app, then select Camera
  2. At the top of your screen, choose the languages you want to translate between
  3. Tap the image gallery iconthen select a photo in your library that contains text

3. Customize your iPhone with widgets

If you haven’t experimented with iPhone widgets yet, we suggest you give them a try.

These handy additions to your Home Screen and Lock Screen let you see information at a glance without having to open any apps. You could have a widget that displays your to-do list, for example, or a widget that lets you scan the nearby area for restaurants at the tap of a button.

Add widgets to your Home Screen

If you want to fill some empty space on your Home Screen with a widget, tap and hold on the area until your apps start shaking. Select the Add button in the top-left corner, then choose a widget and your preferred size.

Once you’re done, hit Add Widget and it’ll find itself a space to sit on your screen.

Add widgets to your Lock Screen

Apple’s iOS 16 update introduced the option to add widgets to your Lock Screen, so you don’t even need to unlock your mobile to check key information.

To add a widget to your Lock Screen, touch and hold on the Lock Screen until you’re able to tap Customize. Then, select the box above or below the time to see which widgets you can add. Tap or drag the widgets you like the look of, then choose Done.

If you run out of space, you can find Remove to delete a widget.

4. Use your iPhone with one hand

If you own an iPhone with a large display, you might struggle to reach the top of the screen with one hand. Apple knows this is the case, which is why you’ll find Reachability tucked inside the accessibility menu. With this enabled, content on the top half of your screen is dropped lower so your thumb can reach it.

To activate Reachability, head to Settings > Accessibility > Touchthen enable Reachability.

  • If your iPhone has Face ID, you just need to swipe down on the bottom edge of the screen to activate the feature
  • On models with a Home button, double-tap the Home button to use Reachability.

You can return to a full screen experience at any time by tapping the upper half of the screen.

5. Explore the pre-installed accessibility features

Every iPhone comes with pre-installed accessibility tools aiming to make the gadget easier to use. These features, which are designed to support your vision, hearing and learning needs, can be accessed at any time.

The full list of accessibility features on iPhone is listed on the Apple website. We’ve picked out three of them below.

Adjust text size

Making changes to text size on iPhone takes just a couple of seconds. To explore vision-based accessibility options, go to Settings > Accessibility > Display & Text Size.

From this screen, you can adjust a selection of visual elements, including Bold Text, Larger Text, Button Shapes (underlines text that you can find), Increase Contract (improves legibility) oath Color Filters.

Magnify your entire screen

Using the Zoom tool on iPhone, you can magnify your screen at any time, whatever app you’re using. You have two options to choose from:

  • Full Screen Zoom magnifies the entire screen
  • Window Zoom magnifies a specific area with a resizable lens.

To set up Zoom on your iPhone, simply head to Settings > Accessibility > Zoomthen turn on Zoom when you’re happy with the settings.

To use it, double-tap your screen with three fingers. You can then adjust the magnification level, move the Zoom lens in Window Zoom or pan to another area in Full Screen Zoom.

Have your iPhone read text aloud

Your iPhone can speak selected text or your entire screen if needed. To enable this feature, go to Settings > Accessibility > Spoken Content. From this page, you can adjust the voice and dialect, as well as the speaking rate and specific pronunciations.

With Spoken Content enabled, you can say ‘Siri, speak screen’. Alternatively, you can tap on a block of text and then select Speak. If you swipe down with two fingers from the top of the displayyou can hear the entire screen.

6. Use Back Tap to take a screenshot

Using Back Tap on iOS 14 or later, you can set up your iPhone so that a tap on the back takes a screenshot – you might find this quicker compared to the ‘normal’ way (pressing the side and volume up buttons at the same time ).

Head to Settings > Accessibility > Touch and select Back Tap. Now, you can choose Double Tap or Triple Tap and then a related action. You can assign taps to the screenshot function, for example, or set up your phone so that three taps activate the Magnifier feature.
