## Description

LuxMapper turns your smartphone&#39;s camera into a lux sensor, letting you measure and record indoor brightness in just a few taps. Results are visualized as an intuitive heatmap, making it easy to check and improve your lighting plan.<br><br>[Key Features]<br><br>■ Real-Time Lux Meter<br>Analyzes the camera&#39;s exposure data to show the illuminance (lux) at your current position in real time. Check brightness instantly — no dedicated lux meter required.<br><br>■ Illuminance Mapping<br>Measure lux at multiple points around a room to record unevenness in brightness across the space. Load a floor plan image and place measurement points for a more accurate distribution map.<br><br>■ Heatmap View<br>Displays measurement data as a color-gradient heatmap. Bright and dark areas are visible at a glance, making lighting imbalances and blind spots easy to spot.<br><br>■ Project Management<br>Save and organize measurement results as projects. Keep data from multiple rooms or locations organized and easy to revisit anytime.<br><br>■ Calibration<br>Correct readings to match your specific device. Adjust the factor and offset for more accurate measurements.<br><br>[Recommended For]<br>• Anyone looking to improve lighting at home or in the office<br>• Facility managers and safety/EHS staff handling lighting inspections<br>• Lighting designers and interior designers checking real-world conditions against ANSI/IES illuminance recommendations<br>• Anyone who wants an easy way to spot lighting unevenness or dark spots<br><br>[Notes]<br>• This app estimates illuminance from the camera&#39;s exposure data; it does not guarantee the same accuracy as a dedicated lux meter.<br>• Measurement accuracy varies by device model and camera performance.<br>• For more accurate results, use the calibration feature.
