Magnifier
Magnifier is like Zoom’s real-world counterpart. It’s a dedicated tool that uses the camera to magnify text and objects around you, turning your iPhone into a pocket magnifying glass. It’s perfect for menus, labels, serial numbers, receipts, and any moment you’re dealing with small text.
Magnifier can also include detection features on supported devices, such as reading text aloud or helping you identify what’s in view. That can be useful not only for accessibility needs, but for convenience. If you’ve ever been in a dim room trying to, you already understand how helpful this can be.
Unlike other features on the list, Apple’s Magnifier is actually a standalone app. It comes preinstalled on your iPhone, but you can also download from the App Store in case you deleted it to save space.
