If you’re a big fan of the audio note-to-self but you’d like more flexibility than the iPhone’s default Voice Memos app, DropVox may be for you. It’s a simple audio-recording app that links with and uploads M4A recordings directly to your Dropbox account.

9. URL Droplet
If someone sends you a file which you are uncomfortable downloading to your own computer then URL Droplet will download the file to your Dropbox just by entering the URL in the box. This is a nice way to create another level of security.
