5 Free Office Apps That Help You View PowerPoint on Android

View Office files on Android devices?

Modern people are always busy working day after day. Office workers like me, have to sit at my computer all day, dealing with different annoying problems in marketing. When I'm off to work, sometimes I can't stop reading proposals on a go (e.g. on a bus). Thanks to technology, I can play PowerPoint on Android smartphone with specific apps. Though Microsoft's Office app for Android is not available yet, these free alternatives allow me to open, view or even edit office files. Here I introduce some of my favourites, all can be found and download on Google Play.
