iPhone and Android app to horizontally reverse/flip the screen (Mirror Image) -- 3

THIS IS A REPEAT REQUIREMENT. I SAW THIS DESCRIPTION ON 'FREELANCER' AND I WOULD LIKE EXACTLY THE SAME, TO REVERSE THE SCREEN ON AN iPHONE NO MATTER WHAT APP IS BEING RUN SO THAT THE SCREEN CAN BE READ IN A MIRROR. THIS PROJECT IS PERSONAL BUT IT TURNS OUT THAT THERE IS ANY COMMERCIAL BENEFIT TO BE HAD I AM MORE THAN HAPPY FOR THE WRITER TO RETAIN INTEREST IN THE APP. Project Description I need a simple Android, iPhone and iPad mobile app that can reverse the screen; horizontally swap/flip (Mirror Image) the contents of the entire device screen, left to right, including text, video, everything, on a smartphone, iPod, iPad or tablet. When this app is started, I need simple way to flip the screen between normal and reversed (mirror image), perhaps a visible "button" or maybe a user selectable location (I'm open to suggestions for the on/off event). When tapped (turned on) the screen should instantly reverse the entire screen and, if tapped again, will put the device screen back to normal view. The interface can be extremely simple. Basically, after activating the app, the only action/event is ON or OFF. I'm ready to begin this project immediately. Please indicate how long it will take you to complete this app when you submit your bid. Thank you If you are one of the people who has made this app for 2 previous projects please mention that when you apply!
