Professional photographers often rely on light meters to capture the highest quality images. But did you know you can measure light with your smartphone? Let's explore the top 5 light meter apps for phones.

1. What is a light meter?
A light meter is a device used to measure light levels, allowing you to gauge the amount of light in your surroundings. With it, you can determine shutter speed and aperture settings. A light meter is essential for achieving proper exposure in your photographs.

Most modern DSLR and mirrorless cameras are equipped with proper light meters. However, many older cameras lack adequate light meter support.
If you don't have the means to invest in a dedicated light meter, using light meter apps can be a thoughtful alternative.
