Best FTP client: FTP on the Go Pro
Cloud storage services have made FTP utilities archaic for many users, but if you work on a website or in many file-management systems, you still need a client. For the iPad, that client should be FTP on the Go, which not only does the FTP uploading and downloading you'd expect, but also provides a basic HTML editor so that you can touch up your Web pages.
App: FTP on the Go Pro
Developer: Headlight Software
