Please read this very carefully. I have an app that I am using for a university study and have the android version. I have been told that it cannot be done for an iPhone. Do you know of a solution?
What I need is an app that causes the screen illumination to switch off at a particular angle of tilt of the screen away from the vertical, and for it to switch on when tilted back to the vertical. If you can we can talk coding costs. I have the UI.
