Five weeks ago, Microsoft announced a preview for the Office for Android and now, Office by Microsoft is officially on Android. Over the last five weeks the company was obtaining feedback from users using the preview apps.
A plus point for Office is that it makes accessing your documents easier, now that it has integrated Google Drive and Box. You are able to review documents on the go in full fidelity while reading/adding comments and you can connect your phone wirelessly over WiFi, use PowerPoint to edit and manage your presentations. Just like on your laptop but you just need to squint a bit.
You can download the app from Google Play for free. Just note that the app might not necessarily run on all Android phones.
