Light Meter + SensorArray

Hardware-Validated Light Metering. Zero Subscriptions. Stop guessing and start measuring with SensorArray—a native, high-performance measurement suite that talks directly to your iPhone’s hardware. Built on international standards (APEX) and professional photographic physics, SensorArray delivers high-fidelity data for analog film, digital cinema, and studio audio. HARDWARE-LINKED SPOT METERING Unlike generic apps, SensorArray utilizes raw 14-bit ISP (Image Signal Processor) metadata. By gating measurements to hardware-ready states, we provide a precision Spot Meter that allows you to sample any pixel in your scene for instant, validated exposure data. THE RECIPROCITY SPECIALIST (Schwarzschild) Master long exposures with precision Schwarzschild Power Law compensation. Film Stocks: Integrated curves for 20+ professional stocks from Kodak, Ilford, and Fujifilm. Automatic math: Meter your scene and get the exact compensated exposure time instantly. THE SUPER SENSOR HUD (Mission Control) A unified interface for critical field data: Ambient Color Balance: Professional Kelvin estimation using McCamy’s Approximation for perfect white balance. SPL Sound Monitor: Calibrated Sound Pressure Level monitoring (30dB–100dB baseline) for ambient noise analysis. NOAA Solar Tracker: Official NOAA General Solar Equations for minute-perfect Golden Hour and Sunrise/Sunset tracking. PROFESSIONAL WORKFLOW SUITE: Digital Film Log: Record Aperture, Shutter, ISO, and Lens metadata for every analog frame. Exposure Equivalence: Built on the international APEX (Additive System of Photographic Exposure) standard. Focus Stacking Assistant: Precision math with a 25% safety overlap for macro composites. Field of View Simulator: Visualize focal lengths from 24mm to 135mm with accurate lens compression. BUILT FOR PROFESSIONALS: 100% Offline: Works in studio basements and remote locations. Privacy-First: No accounts. No tracking. No data collection. Native performance: Built with SwiftUI for ultra-fast response and low battery drain. Own your instruments.
