Google Drive for iOS

The Google Drive for iOS app has been updated with an all-new look that mimics the card-style layout using across Google+ and the Google Drive for Android app.

The good: Google Drive for iOS offers a sleek interface for accessing, moving, and sharing your stored files. Also, the built-in document editors are easy to use and come with a multitude of formatting tools. Real-time collaboration is a nice feature.

The bad: The app doesn't let you create or edit Drawings or Presentations. There are no sorting or filter options to help sift through files. And an extra password-protect feature would be nice.

The bottom line: An elegant blend of Dropbox-like storage and mobile document editing, Google Drive is a must-have app, especially if you're a dedicated Google user.
An impressively powerful mobile productivity solution, Google Drive for iOS mixes Dropbox-style storage with on-the-go document editing. It lets you access and manipulate files in the cloud and do things like create spreadsheets and view presentations, all from its tightly designed interface. The app even lets you collaborate in real-time with other Drive users with whom you share files. As well, it lets you share links to files, so your friends can download items directly from your Drive.

With a recent update, Google Drive for iOS moved closer in line with other Google-made products. It now features a card-based interface like its sibling on Android, and larger thumbnails are available for quick previews of files. Quite frankly, with its sleek look and powerful features, this revamped app should be installed on every Google user's mobile device.

What many Google users may not know is that every Google account comes with 15GB of free storage space. Of course, this space is used for items saved on your Gmail and Google+ Photos accounts, as well as on your Drive, but still, the deal is a good one that's worth knowing about.

Cloud Storage: Thanks to the included space, you can use Drive to store not only your spreadsheets and text documents, but also any other file types you may want accessible from the cloud. From the app, you can upload photos and videos, and they'll immediately appear in your Drive, ready to be accessed from any of your devices.
