iPhone measurement distance can be measured with its own "range finder" app or third-party tools. 1. When using the "Ranity Finder" App, open the application to align the object, click the " " to mark the starting point and end point to measure, pay attention to keeping sufficient light and stable angle; 2. When measuring furniture or rooms, it is recommended to slide the phone on the plane, and use book-assisted or segmented measurements to improve accuracy; 3. If the native function is insufficient, you can try third-party applications such as MeasureKit, RoomPlanner or AR Ruler App to support more shape and high-precision needs. It is enough to use it daily after mastering the skills.

Want to measure distance with iPhone? In fact, it is not difficult, Apple's own "range finder" app can handle it. This function is hidden in the "Practical Tool". After opening it, you can point the camera to the object to be measured, and then click a few more positions to get the length or height.

However, in actual operation, many people will encounter problems such as inaccurate identification and not knowing how to mark the starting point and end point. Let me divide the situation into several situations and talk about how to use it more conveniently.

1. Use the "range finder" app that comes with iPhone

The "range finder" of iPhone is a native iOS application and is suitable for iPhone 6s and later models (but the best one is iPhone 12 and newer models because there is LiDAR lidar).

How to use:

• Open the "Random Finder" app.
• Point the camera at the object you want to measure, and a circle will appear on the screen to prompt you to adjust the angle.
• Click the " " to set the starting point.
• Move the phone to the end point and click the " " sign again.
• The app will automatically calculate the distance between two points.

Tips:

• Try to be on the same plane as much as possible to avoid errors caused by angle tilt.
• Don't be too dark, otherwise the recognition will be stuck.
• If the picture is too messy, the app will prompt "the goal is too complicated", you can try it from a different angle.

2. How to measure the size of furniture or room size

Many people want to measure common scenes such as sofas, tables, and room widths. At this time, please pay attention to:

• Stay stable : Move your phone while measuring the jitters easily. It is recommended to place the phone on the desktop or slide slowly against the wall.
• Utilize reference objects : If you are not sure about it, you can use a book or carton as an auxiliary, and taking a photo first and then marking it will be more accurate.
• Multiple measurements are used to obtain the average value : especially for long distances, such as living room to dining room, and several measurements are performed in segments and then the sum is more accurate.

3. What should I do if the iPhone cannot measure it? Try a third-party app

Some old models may not be enough when they require higher accuracy. At this time, you can consider installing some apps:

Recommended several commonly used ones:

• MeasureKit : supports more shapes and angles, suitable for decoration and design users.
• RoomPlanner : Not only can you measure distance, but you can also do simple indoor modeling.
• AR Ruler App : The interface is simple and suitable for daily rapid measurement.

Most of these apps are based on AR technology, and the principles are similar to those of native rangefinders, but they have richer functions. Before downloading, please check whether your iPhone model is supported.

Basically that's it. Although iPhone distance measurement is not a professional-grade tool, daily household use is enough, the key is convenience. As long as you master the light, angle and stability, the accuracy will not be much different.
