Light Meter is a free Android app developed by Mannoun.Net that provides a convenient way to measure light illuminance using the device's light sensor. The app is easy to use and requires no configuration. It offers automatic sensor readings and the option to calibrate the sensor for more accurate readings. Users can choose between two measurement units: Lux or Foot Candle. Additionally, Light Meter includes an auto-save feature for user configurations.

It is important to note that some old devices may not have a light sensor. In such cases, users will receive a notification upon starting the app. The sensor is usually located near the front camera. The accuracy of the measurement depends on the device's sensor accuracy. If you like the app, you can support the developer by purchasing the ad-free version.
