In fact, it’s technically two iPhone hacks: you’ve got a measurement tool and a spirit level.

Both are in the same app and will make it so much easier when you’re doing a bit of home renovation.

The app is free and comes pre-installed on all iPhones running iOS 12 or later.

You will almost certainly be using a newer iOS, but you can check by going to Settings > General > Software Update.

You can find the app by pulling down on the search on your iPhone and then typing Measure.

It can also be on your home screen.

The Measure app became available as part of the Apple iOS 12 update a few years ago.

It uses smart camera technology to determine distances, giving you reasonably accurate readings of how long or wide objects are.

To use it, simply point the camera at the object you are trying to measure.

If it’s an easily traceable shape, Measure will automatically measure the width and length, and even calculate the surface area of ​​the object.

Alternatively, you can create your own lines and shapes using the big Plus button on the screen.

This will allow you to drag endpoints around your viewer, allowing you to measure objects that are not automatically selected.

You can also use the circle icon to take pictures of what you are measuring.

The Measure app is even more accurate on newer iPhone models that have a built-in LiDAR sensor.

It works by sending beams of light at the person in question and timing how long it takes for them to return.

The phone can map out what’s being focused on and measure what’s in front of it.

It will have LiDAR on the iPhone 12 Pro, iPhone 12 Pro Max, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 14 Pro, and iPhone 14 Pro Max.

But that is not all.

The Apple Measure app also has a spirit level feature.

Yes, your iPhone has a built-in feature that can determine if a surface is level, so you can ditch your giant, clunky spirit level.

tap the Level tab at the bottom left of the screen.

It will show the degree of angle of your phone’s surface.

The feature will also use two white circles to highlight the angle at which the surface is crooked.

If you move your phone to align the circles, the degree counter will reset to zero.

The screen will also (hopefully) turn green, indicating that it’s a completely level surface.
