Dropbox makes syncing and sharing simple: Use it to store, synchronize, and share files and folders so that you can access them on any of your devices.

If you add a file to your Dropbox, it’s instantly available on your Dropbox-enabled iPhone, iPad, or Mac, as well as Windows PCs and Android phones. You can also share your files with anybody who has a web browser. They don’t need to have the app to access the things you share with them.

Supporting so many different devices makes Dropbox incredibly useful. Deploy it for sharing work documents, invoicing clients, collaborating on GarageBand projects, and automatically backing up iPhone photos and various projects.

Every Dropbox account comes with 2 gigabytes of free storage space, and you can upgrade to a whopping 2 terabytes if you subscribe to Dropbox Plus (or 3 terabytes if you need a professional account).

Dropbox is particularly good for teamwork. Share files and folders among colleagues without the hassle of email tag and the risks of lots of versions flying around. It also has a handy scanning feature so you can use your iPhone or iPad camera to scan and share images such as travel expenses or a diagram you’ve doodled on paper.
