Access and view PowerPoint presentations
Platform: iPad, iPhone
SlideShark has been available on iPad for while now but this useful presentation-viewing app has recently been made available for the iPhone too. The app features cloud storage for PowerPoint presentations, which can then be downloaded and viewed within SlideShark, and shared with others.
As with the iPad app, SlideShark doesn't support hyperlinks, embedded videos and a number of other effects but does support all fonts, images, colours and even some animations.
