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 1.1.0
• Choose your measurement area — a new on-screen box shows exactly where the app is sampling, so you're no longer
limited to a fixed full-frame reading.
• Move it: drag the box to measure any part of the scene.
• Resize it: tap − / + to make the measured area smaller or larger for more precise spectrum and color-temperature
readings.
• Smoother, more responsive interface.
