The look
It looks like an old home movie
You can pick a film stock, set the grain and add a sprocket strip if you like. You'll see the look live in the viewfinder, and it becomes part of the film when the roll develops.
Motor zoom to 80×When you slide the zoom it eases in slowly like an old motor zoom, and you can feel a click at each step. How far it goes depends on your iPhone's cameras.
A dial from 8 to 30 fpsAt 8 fps the roll lasts 7:30 and looks slow and jumpy, and at 24 fps it lasts 2:30 and looks smooth. The counter changes as you turn the dial.
You can feel it runWhile you record, the phone hums gently in your hand and ticks as each frame goes through. You can turn this off.
Selfie camera, optional soundYou can flip to the selfie camera to get yourself in the shot. If you say no to the microphone, your film is silent.
