Pointer Remote for PowerPoint and Keynote

Turn your iPhone or iPad into a pointer and controller for PowerPoint or Keynote presentations. Has 'Next Slide' and 'Previous Slide' controls, and can show notes from presentations on the iPhone display along with a timer. Pointer icon can easily by replaced by any image, which could be used for humorous purposes. Touch the screen to show the pointer - which is controlled either by dragging your finger around the screen (easy) or by orientation (takes a little practice) - your choice.
Requirements: Computer running Mac OS X 10.7 or higher, WiFi connection (on the same local network or by creating a computer-to-computer network), and PowerPoint or Keynote (choose the program on the back side of the App). Please note that this app cannot control an iPad Keynote presentation.
A small Mac application, PointerServer, must be downloaded to your computer and started whenever Pointer is used. This program is available for free at:

Please note that the presentation runs on your computer, not directly from the iPhone or iPad. Instead the iPhone/iPad controls the computer.
