Lux Light Meter Photometer PRO

Offers in-app purchases

Free application with many professional tools to measure the amount of light (in lux), reaching the ambient light sensor. The ambient light sensors measure light in lux, a measure of illumination that depends on the amount of incoming light and the area over which it is spread.
Easy and simple. Measure the amount of light and share all results.
The core of the app features is available for free. Some of the modules (PRO) are available after a small purchase. Thanks to this support we can improve the app and build new features. This is not obligatory, but you can support this project by purchasing the PRO version.
The Photometer PRO is a project with a bold vision: Provide free and open access to light measurements and knowledge to everyone around the world.
