Lghtmtr is a simple light meter app to take light readings of scenes primarily for film photography.
Lghtmtr is a great tool for students as well as beginners to film photography to learn how exposure, aperture, ISO are interconnected as the app helps the user better visualize these connections.
The application is very simple: Take a reading of a scene, and then the initial exposure settings are shown. After an initial reading, you can then lock in and adjust the values for shutter speed, aperture, and ISO. Your adjustment will then make the app update the other non-locked-in values. At any time you can review the image which your exposure settings are based on.
