The tape measure feature is an augmented reality (AR) tool that is available on certain iPhone models running iOS 12 or later. Here's how to find and use the tape measure on your iPhone:
1. Ensure that you have a compatible iPhone model: The tape measure tool is available on iPhone models equipped with ARKit, which includes iPhone 6s and newer models.
2. Update your iOS: Make sure your iPhone is running iOS 12 or a newer version. You can check for updates by going to Settings > General > Software Update.
3. Access the Measure app: The tape measure is located within the Measure app, which comes pre-installed on your iPhone. Look for the icon that resembles a ruler on a white background.
4. Launch the Measure app: Tap on the Measure app icon to open it.
5. Grant permissions: If it's your first time using the Measure app, you may be prompted to grant it access to your camera. Follow the on-screen instructions to allow access.
6. Select the tape measure tool: Within the Measure app, you will see a variety of measurement tools available along the bottom of the screen. Swipe left or right until you find the tape measure icon, which typically appears as a yellow ruler.
7. Align and measure: To use the tape measure, simply point your iPhone camera at the object or surface you want to measure. Move the device around until the app detects a flat surface. Once a surface is detected, you can tap on the screen at a starting point, then drag the endpoint to measure the distance between the two points. The measurement will be displayed on the screen.
Remember that while the tape measure tool is a convenient feature on your iPhone, it is not as precise as a physical tape measure. It is best used for quick measurements and estimating distances rather than for precise construction or engineering purposes.
