Lux Meter (Light Meter)

Measure light levels accurately with Lux Meter

Lux Meter (Light Meter) turns your device into a practical tool for measuring illumination, giving you lux and foot-candle readings in a clean, no-nonsense interface. It’s designed for anyone who needs a quick idea of light intensity, from photographers and videographers to indoor gardeners and people checking office or home lighting.

The app reads directly from your device’s built-in light sensor and displays real-time values clearly on screen. A standout feature is the calibration multiplier: if you have access to a reference meter or known standard, you can fine-tune Lux Meter’s readings to better match reality. This is especially useful because different devices can have very different sensor characteristics.

Lux Meter also records minimum, maximum, and average readings during a measurement session. This simple but effective touch makes it easy to assess how stable your lighting is over time, such as when adjusting studio lights or evaluating whether a room meets recommended lighting levels. Additionally, the app exposes sensor data so you can see exactly what your hardware is reporting, which will appeal to more technically minded users.

Being 100% free, Lux Meter keeps things lightweight and focused. However, it doesn’t offer advanced extras such as logging over time, exporting data, or graphing trends, so professionals who need detailed reporting may find it limited. Accuracy is ultimately constrained by the quality and placement of your device’s light sensor, meaning results are best treated as indicative rather than laboratory-grade.

Overall, Lux Meter is a straightforward, reliable companion for quick light checks, delivering essential measurements without clutter or complications.
