How To Use the iPad & iPhone Magnifier

Your iPhone and iPad have great accessibility features, but sometimes, they're hard to find. Are you wondering, "How do I get the magnifying glass on my iPhone?" It's already there! Just open the Magnify app on your iPad or iPhone. You can also adjust brightness, contrast, and color; turn on the flashlight; share magnified images; and more.

Tap the Magnifier app to open it. The app is often in your Utilities folder, but if you can't find the app, search the App Library or ask Siri to open it.
To maximize the view on your display, slide the yellow dot to the right, toward the plus sign. To minimize the view, slide to the left toward the minus symbol.
Below the plus/minus slider are the Brightness, Contrast, Filters, and Flashlight icons. The Filters icon offers a range of filter options, while the Flashlight icon can be used to turn your iPhone's flashlight on and off.
Tap the gear icon to add or remove any of the Magnifier app controls.
Tap Settings.
Now, you can change your magnifying glass app controls. Tap the green circle with a white plus sign next to any controls you want to add.
Tap Done when finished adding controls. You can also remove controls you don't want by tapping the red circle with the minus sign next to each one.
Tap the Image Descriptions icon to see a large text translation of your magnified iPhone screen. Keep in mind this description is not always accurate!
Tap the Focus Lock icon to keep the current image on your screen, so you can examine it without needing to hold your phone absolutely still.
Tap the Camera icon if you want to take a photo of the magnified onscreen image. Tap the Camera icon again to use your iPhone's front camera, instead.
Tap the Shutter button whenever you're ready to take a photo.
This image won't be saved to your Photos app like a regular screenshot, so tap the Share icon and send the image to an app or contact if you want to save it.
