Google Drive is a cloud storage solution available on Android where all new users get 15GB for free permanently upon signing up. You can, of course, buy more if needed. What makes Google Drive so special are the suite of Android apps that are attached to it. They include Google Docs, Google Sheets, Google Slides, Google Photos, Gmail, Google Calendar, and Google Keep. Between the office apps, the Photos app (which allows unlimited photo and video backup), and Keep Notes for note taking, you have apps for practically anything you need to do in terms of productivity. Some of the features of these apps include live collaboration, deep sharing features, and compatibility with Microsoft Office documents. Microsoft Office has a similar setup with OneDrive and Office.

Hulu is an excellent app for watching movies and TV shows for free on Android. It's a free service that relies on ads, but there are some great shows available. You need to pay a subscription fee to access all of the content, but there is a range of excellent shows available without a subscription, including classic comedies such as Family Guy, Seinfeld and South Park.  Android App
Dropbox pioneered the personal cloud service, where all your stuff would be available no matter what device you were using. On Android, it holds its own—even against the highly integrated Google Drive. Dropbox can also act as a seamless backup for your images, automatically uploading every photo to the cloud. It even includes some light image editing tools. If you're the type of person with lots of files already stored in Dropbox, this app is a must-have. Droid App
