Can I use Annotate PRO on my Android device?
You can try to use Word Online on your tablet, but your experience will vary with the version of Android, power of your tablet etc. We don’t anticipate it will be a great experience.
And we aren’t aware of any plans on the part of Microsoft to bring Office to Android tablets.
Google, for its part (as the creators of Android) have been working for years to bring ChromeOS and Android together.
ChromeOS is based on the Chrome browser and is the operating system behind millions of Chromebooks. Chromebooks, by very definition, will never run Microsoft Office. Android tablets cannot run Chrome Extensions, either – which means you can’t use the Annotate PRO for Google Chrome Extension.
