iPhone Has Secret Measure App

The iPhone has a hidden feature that can measure objects using the camera and LiDAR technology. The Measure app, which is available on iPhones from the iPhone 6s and first-gen iPhone SE onward, can be found in the Utilities folder.

The app uses the camera and LiDAR (on Pro models) to measure objects, allowing users to measure lengths, rectangles, and levels. It also includes features such as instant height measurements and guide lines. Pro models, which have a LiDAR scanner, can keep a list of measurements until the app is closed.

The Measure app was released by Apple in 2018, but it hasn't been heavily promoted. It is preinstalled on compatible iPhones, but users can also redownload it from the App Store if it was deleted. Apple added a LiDAR scanner to the iPhone 12 Pro in 2020, making the Measure app more useful on Pro models.

## How it works To use the Measure app, users need to slowly move their phone around to map their surroundings. Then, they can aim the dot at one end of the object they want to measure and tap the + button. Moving the camera view to the other end and tapping + again will display the length on the screen.

## Why it matters The Measure app can be a useful tool for everyday tasks, especially when a tape measure is not available. It can automatically measure rectangles by detecting edges and displaying a white box around the object. The Level tab in the Measure app also allows users to compare the slopes of two surfaces. While it may not replace a traditional tape measure, the Measure app is a convenient feature that can be accessed directly from an iPhone.

The availability of the Measure app on a wide range of iPhone models, from the iPhone 6s to the latest Pro models, makes it a feature that many iPhone users can take advantage of. Whether it's measuring furniture, rooms, or objects, the Measure app can provide accurate measurements using the iPhone's camera and LiDAR technology.
