For stills and motion.

PocketMeter Pro reads the light through your iPhone's camera and hands you a working exposure: shutter, aperture, ISO. Whether you shoot frames or footage, it talks in the numbers you already work in.

For Photographers

Nail the zone before you press the shutter.

Reflected-light metering, the way you'd point a spot meter at your subject. Tap a shadow to place it at middle gray, lock the two settings you care about, and read the third. Kelvin white balance and geotagged frame logs come along with it.

For Cinematographers

Shutter angle, ND, and false color on set.

Switch to Cine mode for shutter angle, iris, and frame rate. 180° at 24 fps reads 1/48, with ND in density notation right on the deck. Flip on ARRI-style false color to judge exposure at the settings you dialed, and range your subject with LiDAR.

What it does

A complete exposure reading, every time you meter.

Point, meter, and get a complete exposure. Built for film shooters and cinematographers who work in stops and angles.

Meter

Real-time exposure read from the camera sensor. You get EV plus a full shutter, aperture, and ISO reading that tracks the light as you move.

Priority

Lock the iris and ISO you're shooting and the shutter tracks the light. Lock just one and it picks a sensible pair for the rest. Whatever you leave open is the number it hands you.

Spot

Tap a shadow and it's placed at middle gray, spot-meter style. Tap back out to overall scene metering any time.

Dial

Tap a value, drag to dial it in with haptic detents, release to set. The other dials move with it as you turn. It feels like a real meter, not a form.

Cine

Shutter angle instead of speed, iris instead of aperture. 180° at 24 fps reads 1/48, with ND in density notation (0.3–1.8) right in the control bar where you dial.

False Color

ARRI-style false color: green is middle gray, pink is skin, red clips. Bands read relative to your dialed settings rather than the phone's auto-exposure.

Range

Distance to your subject in feet and inches on Pro devices, out to about 16 ft (5 m) — the range of Apple's LiDAR. Plus a live scene color-temperature readout for matching white balance.

Log

Save an annotated frame to Photos with the full exposure stamped on it, geotagged to where you shot it. Hold to freeze a reading while you work.

Beta

Testing now on TestFlight.

PocketMeter Pro is in beta with a small group of photographers and camera crew. Public invites open soon.
