Light changes how a space feels. AIL Light Meter is a focused utility for exploring ambient light using your device. It belongs in a small toolkit, with no subscription standing between you and a reading.
Check a spot, plan a survey, revisit saved work or learn how to take a better reading. These are captures of the current Luma Light Meter build.
The meter brings the current reading, lux / foot-candle units and minimum, average and maximum values into one view.
Emulator readings are test values. Accuracy depends on the physical device and measurement conditions.
Focused on the task.
Free across every feature.
A dedicated light measurement tool. Hardware support and reading behavior are being verified in testing.
Designed around the measurement, so the information can stay the focus of the experience.
Get a simple reference for how ambient light differs between places in the same space.
Explore how the available light varies when you move closer to a window or change the surroundings.
Readings depend on the hardware in your Android device. Keep sensor limitations in mind when interpreting a result.
Device sensors vary in availability, range and accuracy. This app is not a calibrated professional light meter. Units, calibration controls and supported devices will be documented after verification.
Offline-first design, all features free and no unnecessary personal data collection are the principles behind every AIL tool. Each app’s actual behavior must be checked before its privacy policy is finalized.
