SpeedUPSI vs PhoMeter

SpeedUp lets you adjust the playback speed of any video on your device. Speed up slow footage, slow down fast moments, or create smooth time-lapse effects -- all without leaving your phone.

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.
