PhoMeter

PhoMeter is a simple white balance meter for photographers, videographers, and creators.

Use your iPhone camera to estimate the color temperature of your lighting in Kelvin and get a practical Tint indication for green/magenta correction. PhoMeter helps you choose a better white balance setting before shooting photos or videos.

Point your camera toward a neutral surface or grey card, wait for the reading to stabilize, then lock and save the measurement.

Main features:

Live color temperature reading in Kelvin
Tint indication for green/magenta white balance correction
Stability indicator for more reliable readings
Lock measurement before saving
Add an optional note to each saved reading
Measurement history
Clean and fast interface for on-set use

Useful for:

Photo shoots
Video productions
Interviews
Product photography
Studio lighting setup
LED light comparison
Checking mixed lighting environments

PhoMeter is designed as a practical white balance reference tool. It is not a professional spectrometer and does not measure CRI, TLCI, SSI, or full light spectrum data. For best results, measure using a neutral grey card or matte white reference under the light you want to evaluate.
