First Things First:
Can’t find Cine Meter on the App Store? If you’re on an iPad running iOS 6, the App Store app defaults to showing only iPad apps. Select “iPhone Apps” at the top of the screen, and Cine Meter should appear.
Is Cine Meter not installing / not starting / crashing on your iDevice? Try a reset: hold down the power and home buttons until the screen goes dark, and keep holding them down until the Apple logo appears (about 10 seconds overall). After your iDevice comes back up, try Cine Meter again.
No picture? No waveform? Readings don't change? Starting with iOS 8, apps need permission to use the cameras, and sometimes iOS doesn't ask you. Exit Cine Meter and open the Settings app. Navigate to Privacy > Camera, and make sure Cine Meter is given permission.
14 October 2014: iPhone 4S and iOS 8: the camera's exposure readout is stuck at f/64+ or f/inf. I've developed a fix, and expect to have it available in a Cine Meter update in early November. Follow @adamwilt on Twitter for updates.
Cine Meter gives you absolute light meter readings, but only relative picture and waveform monitor levels:
Cine Meter’s picture and waveform meter don't use the exact exposure shown by the light meter: they will usually be within a stop of the light meter's exposure, but there is no direct comparison between the two, for reasons described here. You can use the light meter to get an absolute exposure reading, but the picture and waveform monitor only show you relative levels within a scene, not absolute levels based on the meter reading.
You can't preset an exposure or a white balance in Cine Meter. To compare exposure levels or white balances, you need to lock Cine Meter’s auto-exposure and auto-white-balance settings while looking at a reference such as a gray card. The picture and waveform monitor only show you levels and colors relative to those locked settings, not to any pre-determined value.
