The latest generations of iPhone Pro and iPad Pro offer a useful and powerful feature that you may not even be aware of. Built directly into the device, the LiDAR (Light Detection and Ranging) scanner emits a laser to more accurately measure the distance of surrounding objects. An advantage that manifests itself in different ways:
- First, the LiDAR helps the device take sharper photos, especially in the dark.
- Second, the scanner uses augmented reality (AR) to combine the real world and the virtual world. Using AR, your smartphone or tablet can act as a virtual tape measure, show you what new furniture looks like in your home, scan and recreate 3D models.
Introduced in 2020, the LiDAR scanner is available on the iPhone 12 Pro and Pro Max, iPhone 13 Pro and Pro Max, and iPhone 14 Pro and Pro Max, as well as the 2020, 2021 and 2022 models of the 11-inch and 12.9-inch iPad Pro. Nestled between the rear cameras, the scanner can detect objects up to 5 meters away.
1. Take a photo in the dark
Taking a sharp photo with your iPhone can be tricky, especially in low-light situations. Under these conditions, the LiDAR scanner detects the distance to your subject, allowing your camera to activate autofocus more quickly.
Apple says the LiDAR sensor allows the camera to autofocus up to six times faster, which is a benefit when you need to snap the shot before it’s too late. It is not necessary to do anything special for this. Just aim your phone’s camera and LiDAR automatically kicks in when needed.

2. Measure distances
Need to measure a physical distance, but don’t have a ruler or tape measure? Don’t worry, you can use virtual measurement. Included in iOS/iPadOS and downloadable from the App StoreApple’s free Measurements app, can determine the distance between two points, show an object’s dimensions, and tell you if a surface is straight.
Open the Measurements app on your device. To measure the distance between two points, place your phone so that the starting point is the point inside the circle. Tap the plus icon, move your phone along the area to be measured, then tap the plus icon again. The distance is displayed on the screen.

To measure an object such as a square, position your phone in the same way. Tap the plus icon and move your smartphone along the first area to measure it. Then double tap the plus icon. Move your smartphone to capture the next area and double tap the plus icon again. Keep doing this until you have captured the entire object. Double-tap the plus icon at the end point, and the distance appears for all four sides.

To determine if an area is flat, tap the Level icon in the app toolbar. Tilt your device horizontally or vertically along a surface until the screen becomes 0 and flashes green to indicate you are level.
