iPhone
A real light meter in your pocket: spot metering, lockable exposure dials, cinema shutter angle with ND, false color, and a LiDAR rangefinder.
PocketMeter Pro turns your iPhone into a professional light meter. Built for film photographers and cinematographers who think in stops, angles, and zones.
Point it at a scene and get a live exposure reading, solved across real photographic stop tables. Lock any two of shutter, aperture, and ISO, and the third tracks the light in real time. Tap anywhere in the frame to spot-meter: the tapped area is placed at middle gray, exactly like a spot reading for shadows or skin.
• Live scene metering read directly from the camera sensor
• Tap-to-spot metering with one-tap return to full-scene evaluation
• Lockable dials with a priority-aware exposure solver
• Pop-up scrub wheels with haptic detents — it feels like a meter, not a form
• Hold any reading while you work, then release to go live again
• Over- and under-exposure warnings when a solve runs out of range
CINEMA MODE
• Shutter angle instead of shutter speed — 180° at 24 fps reads 1/48
• Frame rates from 23.976 to 60
• ND filters in cinema density notation (ND 0.3 to ND 1.8), right on the control deck — photo mode shows classic filter factors (ND2 to ND64) instead
• False color, one tap from the viewfinder: an ARRI-style exposure map where green is middle gray, pink is skin key, and red is clipping — read relative to YOUR dialed settings, not the phone's auto-exposure
ON SET, IN THE FIELD
• LiDAR rangefinder: distance to your metering point in feet and inches (iPhone Pro models)
• Live color-temperature readout in Kelvin from scene white balance
• LOG: save a frame to Photos stamped with your full exposure — EV, shutter or angle, aperture, ISO, ND, white balance, distance — and geotagged, so you can swipe up later and see exactly where you metered it
• Full portrait and landscape support with translucent controls that keep the viewfinder clear
BUILT BY FILMMAKERS
PocketMeter Pro comes from Studio C-41 and was built and field-tested alongside working cinematographers.
Requires iOS 17 or later. Rangefinder requires a LiDAR-equipped iPhone (Pro models). Camera, Photos, and location permissions are used only for metering, saving your logs, and tagging them — nothing is collected or shared.
