About this app

Measure light levels in any environment. Libre Light Sensor leverages your iPhone's camera to calculate luminosity as measured in Lux. This allows you to determine how much light exposure your eyes are receiving when you wake up, during the day, and before bed in order to optimize your sleep quality.

What's new
