Color meter apps side by side

Six iPhone apps read the color of light through the camera. They differ most in how you pay, the devices they run on, the languages they speak and what else they do: ND, the sun, gels, flicker. This is what each app's own App Store listing says, as of October 2026.

A different kind of meter

A spectrometer is a different tool

A phone app reads light through a camera. A handheld spectrometer like the Sekonic C-800 measures the light's spectrum with its own sensor.
