As far as cloud storage goes, you could do worse than OneDrive (formerly SkyDrive). Sure, it isn’t Drive or Dropbox, but if you are inextricably tied to the Windows ecosystem, it certainly gets the job done. That isn’t to say it could not use a few improvements, though, something of which Microsoft is aware.
Until today’s update, the only way to accomplish switching from your business to personal account was signing out of one and into the other, but now the app fully integrates OneDrive for Business. Unrelated new features let you set a PIN code and access OneDrive using Android’s native file selection menu.
OneDrive is available as a free download on Google Play.
