The Microsoft Office mobile app lets you read, view, and edit PowerPoint documents on the go with your iPad, iPhone, or Android device. You can store files in the cloud and access them from anywhere. The app is designed to work around your schedule by seamlessly syncing the files on your devices to provide online and offline support. You can use the app to open files in your Google Drive or OneDrive account and quickly transfer them between devices. What's more, you can create a document on one device and then continue editing it later on another device. Thus, the app is perfect for co-authoring with others. The app is readily available in both the App Store and Google Play.
