Today, Microsoft announced its unified Office app for iOS and Android. It combines the three key Office apps, including Word, Excel, and PowerPoint, into a single mobile application. As Microsoft says, you'll no longer have to download each individual app.
There's a new Actions pane in the app, and you should be able to use this to complete "common on-the-go" tasks, such as signing PDFs and sharing files. You can also scan documents with your mobile phone's camera, and turn it into a Word file that you can edit, or turn the data into tables in an Excel spreadsheet.
You might recall that before the individual apps ever existed, there was a unified Office Mobile app for iOS and Android. Obviously, this new app is meant to be more robust than its predecessor, adding in newer features that debuted in the years since we last had a unified Office app.
The new Office app is available in preview beginning today. For Android, you can find it in the Google Play Store, where you can sign up for the beta. For iOS, you'll need to sign up for the TestFlight preview.
