PhotoMeterPro
The Pro Light Meter for iPhone
For photographers and filmmakers who want accurate exposure readings without carrying a separate meter. Point your iPhone at the scene, read EV, dial settings into your camera — and get AI help when you need it.
How it works
Three steps from scene to correct exposure on your camera.
Measure the scene
The iPhone camera measures brightness in real time. You see EV (exposure value) — higher means a brighter scene. Use Hold or Spot for precise readings.
Dial into your camera
Switch your camera to manual mode and enter the ISO, shutter speed, and aperture shown in the app. Adjust from there for creative intent.
