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 in 1.1.4:
- Added a Covering Transmittance tool for paired open-sky and under-cover readings.
- Added Measure mode and quality checks for more consistent comparisons.
- Added a Field Guide covering camera direction, reference surfaces, bright lights, and outdoor use.
- Added measurement history and CSV sharing.
- Improved camera reliability and guidance.
Results are relative camera-response comparisons, not laboratory spectral or PPFD measurements.
