I uncovered 8 cool ways to use LiDAR on an iPhone and iPad

Use augmented reality on your iPhone or iPad

Your iPhone Pro and iPad Pro may have a helpful and powerful feature you might not know about. Built directly into the last few generations of devices, the Light Detection and Ranging (LiDAR) scanner emits a laser to measure the distances of surrounding objects. This feature provides a few key benefits.

First, LiDAR helps the camera take sharper photos, particularly in dark conditions. Second, the scanner taps into AR, or augmented reality, to combine the real and virtual worlds, acting as an AR virtual tape measure, showing you how new furniture would look in your home, scanning and recreating 3D models, or immersing you in AR games.

Introduced a few years ago, the LiDAR scanner is available on the Pro and Pro Max models of the iPhone 12, 13, 14, and 15, as well as the 11-inch and 12.9-inch iPad Pro models from 2020 and later. Nestled among the rear cameras, the scanner can detect objects up to 5 meters, or 16.5 feet.

1. Take a photo in the dark

Snapping a sharp photo with your iPhone can be challenging in low-light situations. Thankfully, the LiDAR scanner can detect the distance of your subject, allowing your camera to power up the autofocus quickly.

Apple claims that the LiDAR sensor helps the camera autofocus as much as six times faster, an advantage when you want to take a shot before it’s too late. There’s no need to do anything special. Aim your phone’s camera and the LiDAR automatically kicks in if necessary.

2. Measure distances

Say you need to measure a physical distance but don’t have a ruler or tape measure. You can use a virtual measure. Included with iOS and iPadOS, and downloadable from the App Store, Apple’s free Measure app can determine the distance between any two points, display the dimensions of an object, and tell you if a surface is straight.

To measure the distance between two points, open the Measure app on your device and position the starting point in the dot within the circle.

Tap the plus icon, move your phone along the area you want to measure, and then tap the plus icon again. The distance should appear 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 phone along the first area to measure it. Then double tap the plus icon. Move your phone to capture the next area and, once again, double-tap the plus icon. Continue this way until you’ve captured the entire object. Double-tap the plus icon at the endpoint, and the distance should appear for all four sides.

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

Beyond using Apple’s Measure app, check out other free AR measuring apps from the App Store, including Tape Measure and AR Measure.

3. Try out furniture in your home

Are you looking at a new desk, chair, table, or other piece of furniture and wondering how it would look and fit in your home? Let the IKEA app give you a helping hand.

Start by browsing or searching for a specific piece of furniture or other item, including chairs, beds, desks, sofas, lamps, mirrors, clocks, dressers, or bookcases. When you find an item that interests you, select it and tap the “View in room” button. Choose an area in your home where you’d like to see the item. You can then move the item around the room by dragging and dropping it. When it’s in the right spot, tap the shutter button to snap a picture.

A few other apps that let you virtually position and view furniture in your home are Wayfair, Housecraft, and Bob’s Discount Furniture.

4. Scan a room

Maybe you’re redecorating an entire room and want to measure it to help with your home improvement efforts. One app up to the task is Canvas: LiDAR 3D Measurements.

After signing up for a free account, start a new home project, give it a name, and then kick off your scan. Move your phone to capture every nook and cranny of the room you want to measure. When done scanning, tap the checkmark, and you can view the scanned area and save or share the scan itself.

5. Try on glasses

Need a new pair of prescription glasses or sunglasses but want to check out some options before you head to the store? The Warby Parker app will let you try on virtual glasses to see how they look. Browse the different glasses on display in the app. Spot a pair you like and swipe down from the top of the screen for the Virtual Try-On feature. The glasses automatically appear on your face, where you can check your appearance.

6. Hear your environment described

Designed for people who are blind or sight-impaired, Microsoft’s Seeing AI acts as a talking camera able to analyze and describe nearby people and objects. 

Also: The best iPhone models you can buy right now (including the iPhone 15)

After launching the app, tap one of the icons at the bottom for the item you want to be described, choosing from short text, a document, a product, a person, currency, or a scene. Tap the shutter button and the app should show text and provide a spoken description of the item.

7. Scan a 3D model

If you want to capture a 3D image of an object in the real world, Scaniverse – 3D Scanner is an effective tool. Fire up the app, tap the shutter button, and then select the size of the object you want to scan — small, medium, or large. Move your phone around the object to capture as much of it as possible. Tap the shutter button when you’re finished. Then choose how you want to process the scan. You can view the scan of the object by moving it around the screen, and then edit and share the scan.

Other 3D AR scanner apps worth trying include 3D Scanner App, Polycam – LiDAR & 3D Scanner, and ARama!
