The best office apps for Android tablets

Like Quickoffice, ThinkFree has a nice range of slide-creation tools, including options for inserting text boxes, tables, shapes, and images. The app has just three graphical background options, though. While it's an improvement over Quickoffice, it still restricts the way you can make your presentations look.

The verdictThis one is tricky, as none of the apps' presentation functionality is 100 percent perfect. That said, OfficeSuite Pro's simple and attractive graphical templates make it the best choice for anyone looking to create basic presentations or to edit and manipulate existing presentations. For anyone who needs more finite control over newly created slideshows, ThinkFree may be a better choice, thanks to its superior customization tools -- but know that any presentations you create with it will be somewhat limited in the way they can look due to the app's underwhelming background selection.

The best Android tablet PDF markup programWhile all of our office suite contenders allow for PDF viewing, only one of them provides an option for highlighting or marking up the files: Quickoffice Pro HD.

Given the fact that Quickoffice lags behind other office suite contenders in so many areas, however, I wouldn't recommend spending $20 on it for this function alone. Instead, I'd suggest grabbing Unidocs' EzPDF, available for $3.

EzPDF has a huge number of features, all in a slick-looking interface that translates nicely to the tablet form. EzPDF lets you annotate documents with text or freehand drawing. You can highlight or underline text, add in shapes and images, and crop or rotate preformatted pages. The app can select text from PDF documents, too, after which you can copy it to your system clipboard and use it as needed in other applications.
