About this app

[Overview]
Experience a high-precision light measurement tool that combines the soul of a classic analog meter with the convenience of modern digital features. "Analog Luminometer" turns your smartphone into a professional-grade light meter (Lux) for photography, interior design, agriculture, and workplace safety.

[Key Features]
• Hybrid Display: Beautifully animated analog needle alongside a high-visibility large digital readout.

• Auto-Range: Smoothly transitions from 20 to 200,000 Lux, automatically selecting the best scale for your environment.

• Logging & Graphing: Save measurements with a single tap. Review your data in a scrollable list or a detailed line graph with grid lines and data labels.

• Physical Button Support: Use your device's volume buttons for hands-free operation (Up: Record, Down: Hold).

• Self-Timer: Set a 2 to 60-second countdown for remote measurements. Automatically trigger a "Hold" or "Record" action when time is up.

• Pro Calibration: Adjust result accuracy within a +/- 200% range. Includes a "Calibration Helper" that calculates the correction ratio for you based on a reference device.

[Premium Mode]
By watching a short video ad, you can unlock Premium Mode for 4 hours:

• Remove all banner ads.
• Unlock Data Recording (REC) and Log View (LOG) features.
• Enable automatic data saving at the end of the timer.
