About this app

Measure light instantly with LightSense Meter.

LightSense Meter is a simple, friendly light meter that helps you check the brightness around you in `lx`. Use it at home, at a desk, in a classroom, in an office, or anywhere you want to understand whether the lighting feels suitable.

The app uses your device hardware light sensor for real-time illuminance readings. It does not use the camera. You can see the current light level, follow a live trend chart, compare readings with recommended room ranges, and save sessions for later review.
