Android users can get some extra features like Word count and landscape editing of PowerPoint slides in the July 2018 updates to Office for Android apps.
Version 16.0.10325.20043 of the apps are now available. Most likely, Google Play will update your device automatically.
Word Count in Word for Android
The document word count appears as you scroll through the document, alongside the page position and total pages (e.g. 2 of 12). This now appears to work reliably.

As usual, Microsoft gives their customers no proper information beyond the bare minimum.

There’s also Outlook for Android – which Microsoft promotes mercilessly. You’re better off with the separate email, calendar and contacts apps that come with Android.
