Instant readings

Kelvin, lux, and EV

Get fast measurements of color temperature, illuminance, and exposure value so you can compare warm bulbs, window light, and mixed sources without juggling separate hardware meters.

Balance guidance
Lighting analysis
More than numbers

Guidance you can use

Alongside raw values, see practical hints—like slightly warming white balance, keeping tint neutral, or nudging toward daylight—so adjustments feel closer to a handheld pro meter.

Pro and workflow

Precision when you need it

Unlock deeper metrics such as tint and Duv, CIE x and y, and mired; calibrate to references for repeatable results; save readings with notes, compare scenes over time, and export or share. The developer indicates the app does not collect data from this app.
