Google, Inc. has reintroduced Google Docs and Google Sheets, but this time as standalone mobile apps for smartphones and other mobile devices running Android and iOS.

Both apps used to be available only within Google Drive, a file storage and synchronization service that permits enables user cloud storage, file sharing and collaborative editing. The Google Official Blog announced the release of Google Docs and Google Sheets.

The new Docs app creates and edits documents while Sheets apps does the same for spreadsheets. Both apps are available for Android and iOS and are now on Google Play (Docs) (Sheets) and in the App Store (Docs) (Sheets). A Google Slides app for presentations is coming soon, said Google.

The change into standalone apps also allows broad offline support for both Docs and Sheets. Users can still access your Docs and Sheets from Google Drive.

Users can also retrieve Google Drive-hosted documents and files by using "QuickOffice," an application available for iOS and Android tablets and phones that lets users view, create and edit Microsoft Office, as well as view and annotate PDF files.

Google Drive provides users with 5 GB of free storage. It was originally introduced Drive in 2012 as a way to bundle all of Google's productivity apps together while creating a competitor to Dropbox, a competing file hosting service that offers cloud storage, file synchronization and client software.

Over the next few days, Google will prompt Drive users to download the new Docs and Sheets apps whenever they create or edit files. The Drive app can still be used to view and organize documents and spreadsheets.
