Apple iCloud

Apple iCloud is best if you're using apple devices too. It is useful that it can track your device or other devices, sharing photos or like it'll send straight to your computer the pictures you've taken just a second ago, and other features mostly in sharing. It is also best in security. It automatically (if turned on) backs up your files, like photos, contacts, notes, mails, etc. and secure it like your files are their's, too. Its simple and friendly user interface would be a plus, too. It gives users a less stress and less finding for the things they want to do.

Unfortunately, iCloud is not available for Androids and Windows phone. It also offers only 5gb as a starter, for free, which is not enough for heavy users of camera. It offers a dollar per month for 50gb more storage, which is a good price and other offers if you need a bigger space. This downside is only a bad thing to the people who don't want to spend money on such things. Another thing is that it doesn't give tutorials on what you can do the application.

Overall, iCloud is a great storage application for Apple users. It is offered for Windows PC, but still a little buggy. Everything is great about the app, expect for the storage given at first. Its downside is mostly in storage only, but overall, it is very useful for the users that they feel that their files are stored in a high security application.
