About this app

Prismforge Spectrum Meter turns your Android phone into a real‑time light analysis tool. Measure correlated color temperature (CCT), CIE 1931 x,y coordinates, tint, and an approximate spectrum distribution from the camera, plus ambient lux from the device light sensor.

Features:
- Live CCT readout with smooth updates and color feedback
- CIE 1931 chromaticity chart with live marker
- Spectrum visualization and captured spectral line view
- Wavelength distribution breakdown with percentages
- Recording timeline with pause/resume and file management
- Export to clipboard for recorded data
- Optional FPS, RGB, and foot‑candles display

Note: Results are approximate and device‑dependent; absolute accuracy requires calibration and controlled camera settings.

What’s new

Improved camera stability and measurement consistency.
Fixed recording timing after pauses and background interruptions.
Improved calibration saving and restoration.
Kept the measurement area stable during recording and keyboard input.
Improved privacy controls and English, Korean, and Russian text.

Note: Existing wavelength profiles require a one-time recalibration.
