Whether you're calibrating camera systems on a modular test stand or matching practical lights and studio strobes for a multi-day shoot, SpectralSensor delivers absolute precision directly to your phone or computer. Interface seamlessly with your Imatest Spectral Illuminance Color Sensor (ISICS) and Low Light Illuminance Sensor (ILLIS) to take the guesswork out of your exposure, color science, and system calibration. Multi-Sensor Dashboard: Instantly discover, connect, and manage multiple physical Imatest sensors via secure Bluetooth. Easily switch between devices or run a live "Continuous" polling mode across your entire setup. Comprehensive Metrics: View real-time, exhaustive data readouts including Illuminance (Lux/fc), Correlated Color Temperature (CCT), CRI (Ra alongside granular R1-R15 bar charts), SDCM, Duv, Irradiance, and S/P Ratio. Advanced Visualizations: Analyze your light with highly interactive tools. Scrub through the Spectral Power Distribution chart for exact wavelength intensities, or swipe through live-updating Chromaticity Maps (CIE 1931, 1960, 1976, and CIELAB) that pinpoint your exact color coordinates. Illuminance Tracking: Track lux over time with an interactive history chart. Step away from the sensor and enable "Large Mode" for a massive, high-contrast lux readout visible from across a dark studio. Data Portability: Instantly format your entire data payload into a clean text string for emails using the "Copy All" tool, or save your complete session locally as a comprehensive CSV file. Mock Sensor Analysis: Open previously saved CSV files to automatically spin up a "Mock Sensor." This loads historical data back into the live UI, allowing you to use the interactive charts and scrubbing tools on past captures exactly as if the physical hardware was still connected. (Note: To protect your data integrity, the live recording trigger is strictly disabled when a Mock Sensor is active). Built for working professionals. SpectralSensor features a completely ad-free, distraction-free interface focused entirely on functionality, stability, and accurate metrics. Please note that SpectralSensor is a specialized hardware utility. While the application can be installed and explored using the internal mock sensor mode, live environmental measurements require proprietary Imatest hardware (ISICS or ILLIS), which is sold separately. Take complete control of your lab and set lighting with the official companion app for Imatest measurement equipment.

Verdict

The call

The clearest difference is rating: Imatest Spectral Sensor at 5.0 against Motion Camera's 2.2. Imatest Spectral Sensor also leads on ads (none vs shown) and update cadence (every 6 weeks vs every 6 months). Motion Camera's advantage is ratings volume (5 vs 1) and iOS requirement (16.6 vs 18.6). On price and in-app purchases there is nothing between them.
