In November 2019, Microsoft previewed a new version of its Office app for Android and iOS, combining Word, Excel and PowerPoint into a single application.
Some of the advantages of this unified approach include, according to Microsoft, a simplified user experience and less phone storage used (compared to installing three separate apps). The app also brings new functionality such as the ability to convert images into editable Word and Excel documents, PDF scanning, making quick notes, scanning QR codes and transferring files between devices.
A minor but (to some) important detail: The iOS app supports dark mode, meaning it will be displayed in a darker color scheme to match the rest of the OS when dark mode is set to on.
Microsoft also plans to add more functionality to the app "in the next few months," including Word Dictation, turning a simple outline into a full-featured PowerPoint document, and the ability to see Excel data in a simple "card" format (see below).
The Office app is free to use, and you can use it without signing in, but if you sign in with a Microsoft Account or connect it to a third-party storage service, you’ll be able to store your documents in the cloud. It is initially available in 68 languages on Android, and 20 languages on iOS.
Users who have an Office 365 or a Microsoft 365 subscription will get a number of premium features, which Microsoft says will be "consistent" with the ones you’d get in the previous Word, Excel and PowerPoint apps.
