Editor's note: On February 19, 2014, Microsoft changed the name of SkyDrive to OneDrive and added a few new features to the Android, iOS, and Windows Phone apps. We've updated this review with our impressions of those new features.
Microsoft's cloud storage service OneDrive gives you a place to store photos, videos, documents, and other files in the cloud, so you can access them from anywhere, on any of your devices, regardless of the platform they're running. Like competitors Dropbox and Google Drive, OneDrive keeps the files you store in it safe in case your phone is lost or your computer hard drive fails.
The OneDrive app for Windows Phone is the best mobile version of the service available. That's because OneDrive features are baked into the Windows Phone operating system, and with the app, saving, editing, organizing, and sharing files in OneDrive is seamless. The app is free to download, and users get 7GB of free storage to start.
Design and features
Open up the OneDrive app on your Windows Phone device and you'll see a sleek, minimalist interface, displaying all of your files and folders in either a list or a tiled layout. A quick swipe in either direction brings up pages for Recent and Shared files, while the ever-present, though not at all intrusive, toolbar gives you options to create a folder and move, search, add, and share files. Altogether, it's a simple interface that looks as good as it functions.
The "+" button on the toolbar makes it easy to upload a photo or video right from your device into your OneDrive. You can even set your device to automatically upload photos to the cloud as you take them, which is hugely convenient. However, you must turn on that feature from your phone's Photos app, rather than via the OneDrive app. From the Office app, you can save any new files directly to OneDrive as well.
