Scatterslides ($9.99; Free Trial)
Run your next presentation from your Android phone with Scatterslides. This app can stream your presentation via Wi-Fi to large displays; it can also behave as a remote control for your presentation, allowing you to move from slide to slide by swiping the screen. Scatterslides lets you preview slides on your phone, too.
The app supports Microsoft PowerPoint and OpenOffice Impress files, complete with embedded animations, audio, and video. Note that you will need the free, downloadable Scattershow Player installed on your PC or on a thumb drive to use Scatterslides.
