If it weren't for the existence of OfficeSuite, Polaris's presentation editor would look pretty good. The app offers basic templates to get your slides started; they're far less polished and professional-looking than OfficeSuite's, but they get the job done.
Refreshingly, the app makes an effort to take advantage of the tablet form in this domain, providing a split view with a rundown of your slides on the left and the current slide in a large panel alongside it. (On a phone, that rundown panel moves to the bottom of the screen and becomes collapsible.)
With Polaris, you can insert images, shapes, tablets, charts, symbols, and text boxes into slides, and drag-and-drop to reorder any slides you've created. It offers no way to duplicate an existing slide, however, nor does it sport any transitions to give your presentation pizazz. It also lacks presenter notes.
Most people would get a better overall experience from even the free version of OfficeSuite, but if you want a second option, Polaris is the one.
