What it does

Every tool you need on set,
nothing you don't.

Built for DPs, gaffers, and camera operators who demand precision. No account, no cloud. Your data stays on your device.

Live CCT Reading

Correlated colour temperature in Kelvin, updated 30 times per second from your camera. Tint offset (green-magenta shift) shown alongside — so you see the full picture of what the light is actually doing.

ND Filter Calculator

Enter frame rate, ISO, T-stop, and shutter angle. FrameTemp tells you exactly which ND filter holds the 180° shutter rule — in factor (ND4, ND16) or LTF (0.3, 0.6, 0.9) notation, whichever your kit uses.

Professional Scopes

Four scopes in one: luminance histogram, waveform monitor, RGB parade, and vectorscope. Cycle through with a single tap while you work — the same tools you'd find on a professional reference monitor.

GPS Shot Library

One tap saves everything: CCT, tint, lux, ND recommendation, GPS coordinates, the lens in use, and a frame thumbnail. Add a crew note. Review your full production record in the History tab.

Scene Comparison

Select a reference shot and get ΔK, Δtint, and ΔEV against the live feed in real time. The Match This guide tells you which direction to push the light — and by exactly how much.

Export

Send your entire shot library as CSV or JSON with a single tap. Full metadata — every field — ready for your colour grading pipeline, production report, or on-set notes app.

Exposure Scopes

Four professional tools.
One tap to cycle.

The same scopes you'd find on a professional reference monitor — now always in the phone already in your pocket.

01

Luminance Histogram

Full tonal distribution with highlight and shadow clipping indicators. Know instantly whether your exposure is safe before you roll.

02

Waveform Monitor

Per-column luma trace across the entire frame. Check for crushing in the blacks or blown highlights region by region.

03

RGB Parade

Red, green, and blue channels side by side. Identify colour casts and verify your white balance is genuinely neutral.

04

Vectorscope

Chrominance plotted in hue and saturation space. Confirm skin tone angles and verify colour accuracy against broadcast targets.
