PhonePresenter!

The LibreOffice Impress Remote is an app to interact with your slideshow presentation from your Android device - including slide previews, speaker notes, and more.

Your show. Your way—Keep the pace of your presentation flowing smoothly with the Presenter Display feature. While your presentation appears on the main display for your audience, you can see the current and next slides, your slide notes, a clock, and a timer on a second display. Add Keynote Remote1 to your iPhone or iPod touch and feel free to roam around the room while you present. Using Wi-Fi, Keynote Remote turns your iPhone or iPod touch into a wireless controller. In landscape view, see the current and next slides. In portrait, see the current slide with your slide notes. Tap to play and swipe to advance, wherever you are in the room. »
