This in my opinion is one of the top apps in the App Store. It automaticly will sync your files to your PC, Mac, iPhone or iPod touch and gives you 2 GB of free storage (you can get up to 8 GB of storage if you refer people).

My pros and cons are listed below:

Pros:

• fast syncing of files and documents
• 2 GB of storage (free) which can be built up to 8 GB through referrals
• free app and computer download
• has a security system which includes a pass lock 
• allows the user to add favorites from their files

Cons:

• For people who want to backup a lot of files, this app is probably not for you

Price: $10 a month
