Description by JOHN MORGAN BROWN Written by the developer, not by AppBrain. Click to read.
Nail exposure
Incident metering math built on ISO 2720: dial in ISO/EI, shutter angle, and frame rate to get the exact T-stop — or work backwards from an aperture to the lux you need. Handles dual-base sensors and broadcast gain (dB) too.
Match your gear
Pick from a built-in library of 47 cinema cameras and 241 lenses. Check sensor coverage, mount compatibility, and how a lens, extender, or adapter behaves across your kit.
Director's viewfinder
Frame a shot right on your phone. Choose a camera and focal length and the live preview matches that lens's field of view — pinch or use the thumb zoom slider to find the frame before the camera is even built. Overlay mode draws the exact framing on a wide preview.
Depth & focus
Hyperfocal distance, depth of field, and aperture sweeps with sweet-spot, diffraction, and noise guidance.
Light & color
ND filter stops, white-balance mired shifts, and CTB/CTO/plus-green gel recommendations.
Timecode
Read SMPTE LTC straight from the audio input and show it full-screen, big enough to hold in front of a lens. When the sound has a clock and the camera does not, you film the number. The reader flywheels through dropouts and says when it has lost lock rather than pretending it hasn't.

EXPOCAL gives estimates to support your judgment on set — always confirm critical exposures with your meter and monitor.
