Apple ships a number of hidden and pre installed apps on every iPhone that most users never open. Some are genuinely useful. Some are placeholders for features not yet enabled in your region. We spent two weeks cataloguing every hidden app and what it actually does.

The official hidden apps

Apple includes a Compass app, a Measure app, a Translate app, a Magnifier, and several others that do not appear in the App Store but ship with iOS. Each one is a fully featured tool that most users ignore.

Across the teams and individuals we surveyed, this pattern shows up consistently. The ones who skip the foundational step and jump to the advanced technique end up redoing the foundational work later. The ones who invest the time at the start ship faster in the long run.

The Measure app

Measure uses AR to turn your camera into a tape measure. It can measure length, height, and rectangular surfaces. Accuracy is within 1 percent in good lighting. It can also level surfaces and detect plumb lines.

The Magnifier

Magnifier turns your camera into a magnifying glass for low vision users. It includes color filters, contrast controls, and a flashlight. You can freeze the image and zoom up to 10x.

The Hidden album in Photos
