Looking for a light meter? This app uses your smartphone’s light sensor (on supported devices) to quickly and clearly measure ambient brightness (LUX) and lets you save measurements with notes for easy tracking.

Main Features

• Accurate light meter (sensor-based)

- Real-time LUX values displayed on supported devices

- Clean interface that clearly shows changes during measurement

• Save measurement notes

- Attach notes with each reading (e.g., location, situation, lighting setup, plant condition)

• View measurement history

- Organized list of records by date

- Detailed view showing LUX and notes together

• Check light sensor info

Note

- Light readings may vary depending on device model, sensor quality, and measurement conditions (angle, shadows, ambient light).
