Turn any screen into a stage light. m-BER makes your iPhone, iPad or Apple TV a lighting fixture you can patch straight into your console. Send it sACN, and the screen answers with colour and intensity in real time, just like every other fixture in your rig. No dongles. No gateway. Just join the show network and go. PATCH IT LIKE A FIXTURE • Patch as a Generic IRGB 8-bit fixture on any universe • Set the start address, and m-BER tells you exactly which channels it uses • Intensity, red, green and blue on four channels per region SPLIT THE SCREEN Run the whole display as one light, or divide it into independently addressed cells: • Single: one full-screen fixture • Half: two cells, side by side or stacked • Quad: four cells as a grid, in rows or in columns Every cell gets its own four channels, so one device can be four fixtures. MORE THAN A SCREEN On iPhone, two extra channels put the flashlight and the vibration motor on the desk. Flash, pulse and buzz on cue, straight from your console. BUILT FOR THE SHOW • Orientation locks the moment the fixture goes live, so a bumped phone never flips the look • Clean, full-bleed output with nothing on screen but light • Works across iPhone, iPad and Apple TV.

EXPOCAL is the on-set exposure companion for cinematographers, DPs, and gaffers — every calculation you reach for between scouting a location and rolling, in one fast, dark-themed app. 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. Export Generate clean PDF reports for scene and sensor planning. EXPOCAL gives estimates to support your judgment on set — always confirm critical exposures with your meter and monitor.

Verdict
The clearest difference is in-app purchases: EXPOCAL at none against m's 2. EXPOCAL also leads on update cadence (weekly vs every 2 months) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
