How do I turn my iPhone into a spirit level?

The iPhone spirit level is almost as good as the real thing

Have you just shed blood, sweat, tears and swear words building a Billy bookcase from Ikea? Before you dive into the depths of your toolbox, there’s an even easier way to make sure your collection of Lilliput Lane ornaments don’t fall off and become Lilliput Rubble. Here’s how to turn your iPhone into a spirit level.

One small caveat before we begin: the in-built spirit level tool in iOS is great, but I suggest you rely on a traditional, physical spirit level for crucial installations. I’m not sure Tim Cook would appreciate angry letters about wonky smart TVs or skew-whiff conservatories…

How to turn your iPhone into a spirit level

First, open the in-built Compass app. You may be asked to calibrate it by rolling a small digital ball around a circle.

When you’ve reached the compass screen, swipe to the right to access the minimalist level tool. Hold your iPhone in landscape and you will be shown an angle on top of a moving black line.

But that’s not the end of the iPhone’s tricks. Alongside the level tool, there’s also a way of measuring if a vertical object is straight or, to use the proper lingo, “plumb”.

To access it, simply hold your iPhone as usual and lay its long edge against a vertical surface. Again, you will be given a black line if it isn’t straight…
