Kind of. You do need a tablet in order to use it.
And just not any tablet, the requirements are:
- Android tablet with a screen size of 7 inches or larger
- OS version: KitKat (4.4.x)
- ARM based processor
- 1GB RAM or above
Complained a bit at first start up since I’m running Lollipop on my tablet, but seem to works just fine despite not running KitKat.
Do know that the apps downloads additional files as well, that seems to be rather large so make sure that you’re on wifi before you install.
I kinda liked both Word and Excel previews (will try Powerpoint Preview later), even though it would have needed a bit more display. And, you need to log in with a microsoft account in order to edit apps (possibly even a office365 account, which I used myself).
