Capture screen as movie (for iPhone)

I searching for someone who has done some sort of software for Mac OS or iPhone that captures the screen as a video recording. (note we will not use the camera, we want to record the screen!) In other words some software that captures everything that happens on the screen and compiles it to a video. If you have done such a thing for Mac or iPhone, then I'm interested in your code or if you can be an advisor and help me develop such code (I know programming). 1. Please give an example of your screen-recording software (Mac or iPhone) so I can test it 2. and a fixed price for this function (record screen) 3. and price for help (hourly price) through videoconference The app I'm developing is going to load 1 picture from the photo album. Then when pressing on "record button", all interactions with this picture like zoom and panning/scrolling should be recorded as video until the "stop record" button is pressed. Also the microphone should be on, so if I talk while recording the video then the voice should be saved in the video as well.
